Select All by Unit : Often, even within the same layer, we subdivide fixtures by giving each one different names. Instead the "Select All > by Fixture Type" I suggest creating "Select All > by Unit” (not taking into account the postfix).
How do you use "Unit"? Most US theatres use the unit parameter to indicate an instrument on a fly-bar (numbered from stage left to stage right) independant of channel numbers.
In previous versioins of Capture "Unit" was also used to indicate a location, but that has been addressed in version 2025.
That's it!
