I wanted to request the ability to make vegetation/object groups for vegetation painter. This way I could have a group for painting forest vegetation. A group for leaves and rocks, a group for palm trees and beach objects etc. Also the ability to save these groups to use across multiple maps to make it easier to keep continuity for certain effects across different maps.
Thank you for you time, I hope this is something you could consider in the future thank you.
It has already been requested. Take a look at this thread: https://forums.unrealengine/showthread.php?22908-improvements-for-foliage-mode&highlight=improved+foliage+tool 
But they are working on something like a new foliage tool:
From what was said in the twitch the ecosystem would operate like Vue 11’s echo system where you populate segmented sections on random. Where you don’t have any manual controls. This would be for manually controlled spot painting for misc. Thanks for the links.
