An Add Form is what you get if you use a Show Form Screen Action, or enable the Add Form option on a list screen, or use a Form Button. You can tell when you’re in a native form, as you have the Cancel/Add options at the top of the screen.

Once you are done filling out the form, you can have a button with a custom action that will first have an Add Row action that will take those user specific column values and write them to a different table. You can then follow that action with a Set Column action that will clear the user specific columns so it’s ready fo…
