Inbox for submitted forms

Hello,

     Is there a widget that will store all of the submitted forms that I can select and edit as needed?

    We are planning to use it for event invoices and will have several active at once.

I am not sure if I understood your question correctly. Do you want to combine submissions of several forms in a single report? If so, please check our Combine Submissions app - https://apps.jotform.com/app/combine_submissions

If I did not understand your question correctly, please explain in more details what exactly are you trying to achieve.
