Is there a way to default the vendor loc when creating an invoice?

Is there a way to default the vendor loc when creating an invoice for multiple users?

Example:

Vendor 1 - VNDR_LOC: MAIN

- VNDR_LOC:TEST

Create a Voucher using different users:

Can User 1 be setup to always default to MAIN and User 2 be setup to default to TEST?

User 1: VNDR_LOC: MAIN

User 2: VNDR_LOC TEST

Thank you.
