Curtain Wall - Edit Scheme rebuild after every change

[2D]

When entering edit mode in a curtain wall, every change of the curtain wall scheme in a 2D view requires a rebuid, before the ability of moving scheme lines is active again - even with all geometry turned off.

Step 1 - move a scheme grid line

Step 2 - try to move another scheme grid line without rebuilding your model...

At least for this situation - when all geometry is turned off - this requirement of rebuilding should not exist. It costs a lot of time and is also very annoying.

Yep, some custom editing commands should always be able to maintain a connection with the scheme.

It shouldn't be that hard to maintain panel customisation while editing the scheme.
