I have a field with a subgroup, which is clonable to produce product variations. Every clone adds "Entry N" in a post UI field. Is there a way to name these accordion titles from some text field in that sub-group, instead of Entry 1, Entry 2 ... Entry N? For a large number of product variations that would be very handy.
Thank you for pointing me there. If I have a group defined from UI, can I add filter for sub-group titles only using PHP function, or I have to delete group created from UI and then re-define the whole array programmatically?
