?Lightroom Smart Collection size option?

[Krang]

Can it be that adobe has omitted this option as a filtering method? I would like to make a Smart collection for all my panoramas, which are quite numerous, and I'm too lazy to tag everyone of them manually.

Am I just blind? Is it possible that you cannot sort according to size in smart collections?

Thanks for your help!

I believe that's true.
You could probably sort thru the catalog by camera and/or lens and eliminate most of the stuff. This is where "Keywords" work magic.
