I would like to create a relationship between multiple CPTs but from what I can gather post relationships seem to be limited to 2 CPTs?
I have 3 different CPTs, let's say "CPT-1", "CPT-2" and "CPT-3".
I am planning to create another new CPT called "Offers".
I would like to be able to link an "Offer" to multiple CPTs and vice versa. So for example, I have an offer called "Offer A", I would like to be able to link it to a post in "CPT-1", a post in "CPT-2" and a post in "CPT-3". And these posts may be linked to multiple "Offers".
Is this possible? Or would it be case of setting up a number of separate many-to-many relationships?
Essentially what I would like to do is have the "Offers" show up on the single post pages for "CPT-1", "CPT-2" and "CPT-3" (using the example above "Offer A" would show on the linked post in "CPT-1", the linked post in "CPT-2", and the linked post in "CPT-3"). And then the single post page for "Offer A" would show the linked posts from "CPT-1", "CPT-2" and "CPT-3").
