Adding favourited images to a contact form

I’m using Jetboost to filter and favourite images from a collection. I need users to be able to add these favourited images (max 6) to an enquiry form. This is a feature needed to be brought over from my clients old site build in WP – First Step Designs | Contact

Can anyone help with the workflow on this? Is it possible using Zapier or similar integration?

The site is still being built but here is the read-only link:
