Haas Vf-2,macro For Tool Life

[Tulak]

Hi to all
Can someone please help me.
I am running 14 pallets with same dia cutter which is replace after each third
pallet.I have macro set for checking broken tool which I like it the problem is that machine do not knows how long to use that cutter.
I know that one cutter I can use for 75 minutes which is for 3 pallets.When broken tool is detected say after second pallet it will put next #2 cutter(sister tool) but after third pallet it will take #3 cutter so cutter #2 was used only 1/3 tool life.
But my goal is how I can set tool life .

Here is a part of sub PGM which calls up pallets:
