Am I able to insert a link that will allow users to submit another entry if they have multiple entries to key

Perhaps you were looking for a multiple entry kind of field or widget. You can check those available widgets here https://widgets.jotform.com/category/multiple_entries

How about the Dynamic Textbox widget.

Here is a demo form https://form.jotform.com/61654058786972

Hope this help. If this is not what you need, please provide us with more details on what you require and we will look for better resolution.

Thanks.
