Landscape's Region Selection Tool

I’ve been using the Region Selection tool in Landscape mode to mask different areas in the landscape that I don’t want to change as I’m sculpting the area. As I’m doing this, I was wondering if there was a way to save the select region so that I could come back to it later and not have to re-select the area I was working on again or have to finish sculpting the area before closing Unreal. If this feature doesn’t exist, may I ask how people get around to doing what I am trying to do?

You could submit a feature request, but I don’t think there is a built in way to do this yet.
You could possibly script your own python applet to deal with it if you were so inclined…

Alright. I thought that would be the case, but thank you for taking the time to answer.
