Sorry, my English is so bad that I have difficult to explain correctly.
I did photo shoot and i like to see all images in B&W.
I did clone for all images and I created a clone variation.
Some times I want export only B&W version, but with 900 images is hard select manualy, or boring

When I create clone variation I can see little number like "filename-0002 [2]" this number identify the variation, but I can't filtering.
I like some filtering like we have with stars or color tag, but for variations, I want to filtering only 2st variation, or 3th variation.
Do you understand?
Sorry if I not explain very well yet.
