Question/Feature request: can i parse if a player is a region owner / member or one of them?

[WataLaker37821]

hi, can i somehow parse if player is an owner of a region? I am trying to parse %worldguard_region_owner% placeholder so it will make an ExecutableItem work only if player is an owner/member of a region, also i tried to parse with string placeholder, but still, it says that im not an owner of that region.
