Dark frame selection also by SN

Hi, I’d new here, so please forgive, if I put this in a wrong spot…
Anyway this concerns RawTherapee’s dark frame selection logic described here Dark-Frame - RawPedia .
I would find it useful and logical, if there was a check on SN. It’s after all the camera’s chip that does the hot pixels, and each camera has it different. Some people may have multiple cameras of a same model. I might be able to make a patch myself, but if someone feels like doing it quickly before I spend time finding where and how, that would be probably better. Or at least point me in the right direction. Thanks.

So, I decided not to wait. This patch works for me. Probably by some accident, I added the SN also to ff search, which I don’t use…
