I have a small suggestion for the next update of TMC Polygon Insert Tool.
I suggest the following BlendIndeces get replaced with "MOT02_Chest" instead.
Or why not a small box that lets you pick the bone to replace the unfound BlendIndeces?

These BlendIndeces was not found.
Replace with BlendIndex of "MOT01_Head" and Continue?

02 / OPT_Breast_Left_tip
03 / OPT_Breast_Left5
0C / OPT_Breast_Left4

10 / OPT_Breast_Left2
