Hello!
So far, I am loving Pods… It’s been a real lifesaver.

I’m building my client a mini portfolio website but I’m a little stuck with something, so I’d love your thoughts/feedback.

I have two primary custom post types: ‘Projects’ and ‘Ranges’.

The ‘Projects’ will feature lots of different types of products: lamps, chairs, sofas, etc.

Whilst the ‘Ranges’ will be more of a blog on different styles: ‘Scandi’, ‘Vintage’, etc.

I want to be able to display a “Related Posts” style section on each single ‘Ranges’ page, but it would say “Featured in this range”… And I want the client to be able to manually select what ‘Projects’ are displayed on this page when they’re editing each individual Range pages.

Is there a way for me to create a new Field on my Range post type that displays the entire list of ‘Projects’, and my client can essentially click which ones are applicable?

Any thoughts if this is possible?
