Flatten(?) Layer

I do not even know if this would be possible. However, having a dedicated layer to flatten and later un-flatten stamps, saving on lag and working within 100k stamp limit. Until now, I have not been even able to reach this number of assets on a map, but in lew of some new big world map projects, the limits of my own pc, the un-optimized nature of using a browser to run Inkarnate, and the 100k stamp limit has been forcing me to downscale the editing quality of my map, as well as making me flatten large areas of places I would have liked to keep editing capability. I know that its not just me who is effected by this problem, but many of the advanced world map creators. I appreciate the time and effort put into these sort of updates, and think something like this would be perfect to release alongside the Inkarnate 2.0 update.
