I have a many to many post relationship between custom post type A and B. The relation has an intermediate post type. I had planned to add a repeatable field group to that intermediate post type. But Toolset only allows me to add single fields, not a repeatable field group.
I know that repeatable field groups can only be used if the field group is assigned to one post type only. In this case I only want to use the repeatable field group for that one intermediate post type. Yet I can't.
Is this indeed not possible? If so, what's the best alternative?
The only alternative I see to this is to either add the repeatable field group to one of the Posts in the relationship. The reason why it isn't possible is because the intermediary post type is essentially created solely for the purpose to function with the relationship setup. So it is not allowed.
Thank you. Adding the repeatable field group to one of the posts in the relationship could work in my case if it would allow a post reference field in a repeatable field group. But it doesn't, so I will try to solve this with a non-repeatable field group in the post relationship.
