Save Custom Avoid Lists

I was wondering if a feature could be added to have custom lists of “avoids.” I saw that there was a new “avoid Russian Airspace” feature, but was wanting to have a custom list (as well as the ability to add/remove items from said custom list) to allow for things like avoiding Ukrainian airspace, and for instance at the moment avoiding Israeli, Syrian, Iraqi, and Iranian airspace without having to manually add each FIR for every flight through the region

See here:
