Labeling diffuser cal louts with (TYP 2) if they are in the same room or near each other.
When the same diffusers are located in the same room, it would be nice if there was an option to label one diffuser and then (TYP and then the quantity it applies to) as opposed to labeling each individual grille/diffuser. This would help clean up the drawings quite a bit from unneeded notations.
It is currently possible to manually label your diffusers this way. The DM HVAC->Diffusers->Remove Callout command can be used to remove the unwanted callouts. Then you can add the TYP label using standard AutoCAD text.
