Does Altium support the creation of a separate drill table for back-drilled vias? If not, I figure I could use a unique via size and specify the controlled depth drilling info in the fab notes, but I was hoping that Altium supported it directly. Anyone have any tips or suggested methods regarding this?
Edit: Just in case, I'm using the latest

It is a process to remove the unused section of plated through holes.
This will ensure signal stubs are minimized; Stubs are the source of impedance discontinuities and signal reflections which become more critical as data rates increase. It is preferred method in HS designs.
Allegro handles back drilling processes.
