Adding selection options / prompt per region options to live-mode

[dauwpe]

Hello,

while Live mode is fun to use, there's one (or a few?) things that make it sometimes difficult to use effectively. As it seems to me currently, whenever you create a new region, the underlying regions prompts are still applied to the new region you just created.
(Correct me please if this is not the case)

As I understand it, if you for example have a region "a field with flowers", and add a region "a tree", it can still happen that things like the "flowers" still get applied to the "tree" when drawing in. This is certainly desirable in some cases, but not all. Sometimes Id like to quickly sketch in entirely new objects with no relation to previous layers.

In Generate mode this can be solved with unlinking regions or using different fill methods. Live Mode doesnt allow for that afaik.

Would it be a huge mess to allow for the same options in Live mode as in Generate mode?
