Not being able to use a Room Name or Number as a label within an equipment tag is limiting.
I use room number in many unique references for AC units, MVHRs, Fans, Radiators etc. It enables the tagged unit references to be utilised throughout the supply chain without having to cross reference drawings and schedules. You instantly know what room things are in simply by the reference. For Example AC/100/A = AC Unit A, in Room 100.
I could make a shared parameter and enter it manually but that's tedious and unnecessary.
