Hello @JennyM84
Indeed a good one; I gave my vote. Remember you can vote for your own submission too! The more votes, the highest the possibility that the request will get prioritised.
In the meantime, I wouldn’t say there is an obvious way of doing this, but there is a way
Check out this post by Bastien, you can import a CSV file into a project to create the custom fields in the project and then from within the form builder you can connect that specific custom field.
Cheers,
