Tracking & validation using a form

Hey community,

I'm wondering if it's possible to do tracking (accept/decline) using a form when other information already exists. This is a little confusing, so let me explain it better with an example:

If the information in the picture below already exists on a sheet, is there any way - for example - for Jill to fill out a form accepting her role on team Red in 2021 and have that "accept" show directly into row 1 under the Accept/Decline column without creating a new row? Does Smartsheet have the capability to do this kind of validation?
