Conditional commands?

[Beholder3]

Hi,

is it somehow possible to have a conditional command sequence?

Background:
I would like to these commands:

Code Select Expand

-exif:LensModel<makernotes:LensType -XMP:Lens<makernotes:LensType -exif:LensInfo<LensID -exif:LensMake<LensManufacturer
on all pictures I select but the following ones

Code Select Expand

-exif:FocalLength<copy2:FocalLength -exif:FocalLengthIn35mmFormat<Calc35mm
only on files where copy2:FocalLength is less than 10 mm.

Currently I do this by running twice over the files, first processing all files and then running the latter part only on the ones in focal range 8-10mm.

I would like to do this using a single run to save some time.

Is it possible?

The application can't do this in a single pass.  The only way to do this in one pass would be to write a Perl script using the ExifTool API.
