There are a few ways this can be handled with various levels of difficulty and power gained.

A very basic example could be;
Look at the ladder for bit F64.2 which indicates that the tool life for the "currently used tool" has expired. Also look for F64.1 which indicates A new tool is selected. See if per chance they turn on a macro DO (g54 - G55 which equates to #1000 - #1015) that you can read in the Part Program. If these are available you could generate a sub to set the active wear offset to 0 based on criteria you decide.

The best resource for tool life operation at this level may be "Connection Function" manual for the control.
