Build Masks from a combination of tools

What problem do you see this solving?

At the moment only one tool can be used once in a mask: brush, one gradient, one radial gradient. You cannot combine two gradients into one mask or substract a gradient from a brushed mask etc. These things are possible in other RAW-converters forever and make masking so much more flexible. I know everybody is talking about AI masks, but in C1 even those basics are missing. To be clear: the tools themselves are fine (Magic brush is good, Mask Refinement option is great!)

When was the last time you were affected by this lack of functionality, or specific tool?
