Possible? HowTo add 'bulk' snapshot labels to bunch of .dng's for ACR / LR?

I don't know if this is possible, but thought I'd ask.

Can ExifTool add a "snapshot label" with all the current ACR / LR settings to a bunch of .dng's?

Something I regularly do is start with a series of .dng's, and "play around with them", especially when I'm trying something out (like MagicLantern's DUAL_ISO or AUTO_ETTR, or QpCard's QpCalibration, etc.). I prefer to put a snapshot label as I progress through what I'm playing with, such as:

• A AsShot, PV2010, AcrDefaults, AdobeStandard
• B WhiteBal, Normalize DynamicRange with SpyderCube
• C PV2012
• D Renormalize DynamicRange
• etc.

Within ACR, I'll go to the far right icon tab (Snapshots), click on the small icon near the bottom right to open the "Create Snapshot dialog" (next to the trash-icon), and make the first "Snapshot label" (such as "A AsShot, PV2010, AcrDefaults"), then Select and Ctrl-C to copy the label into the clipboard. Then I'll do a series of

• Down arrow to the next image
• Click on the "Open Create Snapshot Dialog" icon (near bottom right next to trash-icon)
• Ctrl-V to paste the saved label
• Enter key to Save the label (so all ACR settings now saved and associated with that label)
• Repeat for rest of images

This isn't too bad for a few images (dozen or so), but gets really tedious for a significant number. Also error-prone.

At first I thought it might be a "piece of cake" to select all images within ACR, and then create a "snapshot label". However, my experience is that this just makes a snapshot label for the "most selected image" rather than all images. Drat. Perhaps I should try in LR?

Is there a way for ExifTool to accomplish this, or the equivalent? I'd like to have a command-window opened in the folder with the .dng's, and run an ExifTool command (or script?) to accomplish something like the above?

Or is there some way to accomplish the above (or equivalent) with ACR or LR or PS or some other utility? My observation is that ACR / LR don't have the equivalent of Photoshop's Actions or Scripts, but perhaps I'm mistaken.

I can't answer this question because I don't know what adding a snapshot label does.

But if you compare the metadata using exiftool -a -s -G1 before and after adding a snapshot, then you can do the same thing in ExifTool provided that all of the changed tags are writable by ExifTool.

It's almost certainly more of an ACR / LR question. Briefly, a snapshot records all the changes you've made to a RAW file. I don't think it has anything to do with EXIF info.

I just thought I'd check, as so far ExifTool has greatly exceeded my expectations, and I had my fingers crossed that ExifTool might have some way of doing that.

I'll check with forums that are specific to ACR/LR.
