What is the general goal of the feature?
To make setting permissions and users for each form easier.
To make it possible to add/remove a user from multiple forms in one go instead of individually.
What are the most likely user stories for how and when this would be used by someone on your team?
Admins would save a lot of time adding/removing/editing users for accounts with many forms.
Can you sketch out graphically how you think this should look/work in practice?
There can be a page to add eligible users to the account.
There can be another page with a table having these eligible users on one axis and forms on the other axis. Each intersection can be a checkbox to activate a particular user for a particular form.
How useful would this feature be to other users or organizations?
