If it is a consistent amount and predictable wear, one Q&D solution is to program to rough to half the amount, stop spindle, move tool, M1 to pause, change insert, S to restart, move tool back and restart cut. On a similar note, I have a lathe with a 6T Fanuc control. It will let you pause, move tool, do whatever, and restart cut, The caveat is that the tool has to be moved back to the EXACT position that you moved it from at pause.
