How to embed GF in sidebar to edit a PODS table item?

I want to embed a GF form in a page sidebar that will allow very simple editing of an existing PODS table item selected from a list displayed on the main page. This approach is an alternative to editing the item by redirecting to item’s archive page (and using a GF form associated to that archive).
I know how to embed the form in a sidebar, and I can use $JQuery to populate the form key value with the item’s ID value. However, I want to update an existing item rather than creating a new item.
My plan is to apply this method to approximately six PODS tables, therefore I would like to develop a standard approach.

Has anyone had a similar requirement? If so, any thoughts on a solution?

Thanks.
