not sure if its possible, but every wipe i setup some roleplayshops together i have in my copy paste. it would be cool if i can name them on the ingame map, like all monuments are named. for example adding ''town'' on grid ''T9" or adding ''Admincabin" on grid ''S4". 

You could try this https://umod.org/plugins/marker-manager
The only other way i know is build this stuff in rustedit and give it the Map Marker there.

Just FYI:  with RustEdit, the prefab name is "Monument Marker", then edit the label to whatever you want.
