Ability to save "regions" that you can choose from

It would be nice to be able to save pre-defined "regions" that you can either assign shortcuts or, upon pressing the function to initiate capturing a region it asks which saved region you want to capture.

I often use regions for work and personal that requires I capture the exact same area without deviation (even by 1px) for different projects.

Instead of having to re-set my capture region each time I jump back and forth between projects, it would be nice to be able to save pre-defined regions so I could just set it once and choose between the ones I want.

Hopefully this makes sense.
