I have a similar request -- we have an agency, and a number of projects available. I'd like the ability for a user to click a button/link to be able to "claim" a project.

This could be implemented with a mailto: link that could hit a specific mailhook to process the request, but we'd need the ability to include the specific user's email address in the body/subject, as well as a unique identifier for the project (Eg: we have a project ID field in Airtable).

Just need the ability to use these fields in the action buttons (for example, an action button that POSTs custom data to a webhook could work)
