[Forums] Go to next record in a form

I want to use a form to update records in an entity with 11 attributes. I am trying to avoid using a table format as there are too many attributes to display across a row.

I have created a Save button which works fine but I cannot find a way of moving to the next record without exiting the form. I can see a CurrentRowNumber which is available in an IF but not in an ASSIGN. In the absence of something builtin, I was intending to create a Next button (and a Previous).

It looks as if it should be simple to achieve but I noticed that the tutorial example left the form to choose another record.

Is there a way?
