Shortening parts' primary.secondary revision scheme to show only primary revision level in assembly BOM

We use primary revisions for product design changes.
We use secondary revisions for minor documentation changes.

People get freaked out when they see "02.004" listed in the revcolumn of a BOM.
We would like to set up part templates that would report only theprimary revision in an assembly BOM.

Can I set up a part template's DT to get the current revision ofthe (eventual) part when opened from the PDMWorks Vault: "03.005"
and have it return the interger: "3"
which would in turn become the part's custom property that would bereported an assembly's BOMs reevision column.
or
would I try to do this in an Equation in our SW templates?
