If there was some situation where incorrectly positioned studwork could potentially cost tens of thousands of pounds in sound testing or reconstruction, or refused building regulation applications, and we could graphically convey the correct information on plan then we would probably want that ability also Robert.
The reason referring someone to a detail isn't a good solution is because the 1:50/1:100 drawings actually conflict with the details (and we've experienced problems in this regard). The only way, currently, to avoid this conflict on our drawings is to either draw the junctions manually, as explained above, or to remove all the hatching from the walls on the 1:50/1:100 drawings. Both options are less than ideal.
