I'd like to request a scripting command that checks if unit can reach vehicle's supply point, as in if it has "Inventory" action and associated actions like "Assemble" visible. The check seems to be rather complicated in the engine so having the engine do it instead of trying to solve it through scripts (which I couldn't) will be useful.

Suggested syntax:
BOOL = ENTITY canReachSupply ENTITY.

Usage would be:
player canReachSupply _weapon_holder;
