"Infinitely" expandable data entry on JSM form

[shardern]

We are looking at making a tool that allows a user to make new elements for a project automatically.

One of the important parts of this is the ability to add other users at various access levels to the project in the form.

So, for example:

user1@email.com | User

user2@email.com | Developer

etc.

I am unsure, however, if there is a way to allow the user to add additional rows to a table to allow for as many users as they want, or if we could implement a repeatable section that adds that same 2 fields to the bottom of the form every time to allow for as many users to be added as possible. 

If this sounds like something someone else has worked on and if there are any suggestions, they would be much appreciated. Additionally, if anyone knows if there is a suggestions ticket open with Atlassian to introduce this, I'll get my team to go vote for it.

Thanks in advance!
