How do you update supplier request (supplier onboarding) in PS once it's submitted for approval but

We are on PS 9.2 image 11.  We have noticed that once a supplier registration has been entered and approved, the address and location descriptions are generic (i.e. Address 1, Address 2, Location 1, etc.).  We want to update these fields prior to the request going through workflow. Has anyone done this before and how?

Thanks,

M
