Make number of form submissions available in campaigns

My idea is:

We have multiple clients using Mautic landing pages and forms to set up event subscriptions. We’ve got asked a few time if it was possible to limit the amount a form can be submitted to then hide the form or put the new submissions on a waiting list.

We’ve been trying to - on Drupal side - get the number of submissions from the Mautic API and put it in a hidden field in a Mautic form but that has been such an overkill.

It would be great if we could use the number of submissions in a campaign and set actions accordingly.

I think these groups of people would benefit from this idea: Any Mautic user who wants to use forms to have people subscribe for anything.
