Assign Data to User

I have a database where the public enters in data (application) this data then goes into a repeater on a dashboard page. The dashboard page is accessible by our applicant reviewer. Upon successful application review, the reviewer needs to assign the application to a consultant from the repeater. I have a database of consultants and each will have their own dynamic page. I just need to know how I am able to assign it to that person from a repeater.

Take a look at the article on how to create a page that displays items based on the currently logged-in user
This can give you an idea of how to display specific information for specific users, for example a specific application by user for specific consultant.

Check out this forum post to get an idea about assigning form submissions (applications etc): https://www.wix.com/corvid/forum/community-discussion/assign-a-submitted-form-to-specific-member
