Altered Revision In BOM

We receive models from one of our customers. Their revisionin the properties looks like this (A01.002). For us the rev levelis A01, we ignore the decimal point and everything to the right.

Is there a formula that I could setup in the BOM to only show whatis to the left of the decimal point?

I used to change the property in each model, but that gets to betime consuming.
