The website I'm currently working on is a plattform where several 'subgroups' can post events but also have their own subpage. So the two affected secrions are 'event' and 'subgroup'. Currently, every subgroup has an account which is author of their entry and they can create new event entries (which are linked through an entry field).
I'm wondering if it's possible to have multiple accounts for a subgroup which have the permission to edit their entries but not the ones of other subgroups.
Long story short: is it somehow possible to assign an entry multiple authors?
