Multiple items from single form input

Hi, I’m developing a workflow where clients make design requests to us through a form. Often clients submit a “recurring request”, where the same basic design is needed multiple times, but each with minor adjustments in information (e.g. text change) for each request. I would love the client to be able to set this from one form submission, rather than needing to revisit the form multiple times and type in the same information.

Do you have any ideas about how clients could be able to quickly create multiple items on our board, from one single form request?

Thanks for your help
