I haven't tried or looked into separate stacking like i think you are talking about?
So it sounds like you stack all your Bias frames first, this generates a master Bias.
Then you load all your lights and Flats in and the mater bias then stack
these?

It seems like a long way to go about it
You should be able to just chuck your lights and calibration files into DSS without targeting each stack separately. I have never done anything else when I used to use DSS.
btw, TIFF or FITs is fine. I just stick to FITs for the main astronomy programs, then change it to TIFF when I export to Photoshop for the final touch ups.
