Restrict duplicity check for Tax Number in Vendor Master

Hello,

     Is there any way to restrict the duplicity check for the Tax Number 2 for only one Vendor Account Group?

     I´ve seen that accessing the tcode BUPA_TAXNUMTYPE it´s possible to turn on the check on the field, but this change will impact in all Account Groups that use it. I need that this check be done in only one in specific.
