Airtable is wonderfully optimized for internal user teams. We are trying to build a simple app for external users.
We want to enable external users to enter data into a series of linked tables as part of their signup process, with the ID created for them in the initial table used to follow them through the other forms as they move through the linked tables entering data. Basically, if a form could hand off an external user to another form with the ID prefilled dynamically for each subsequent form in the string. This ID is the relational field in all tables.
We know how to use trigger actions to update tables, but we want to have a separate form for each table, with their identity established in the first table moving with them from form to form in a single session.
