because of my workaround for this issue I occasionally need to add event participants with the role of "guest" via the admin backend. That's ok, but when I register a guest this way I'm not able to specify the "registered by" data that gets added automatically when an Attendee registers himself and multiple others using the frontend registration form. I'd like to have this info because I need to know which participant the guest belongs to.
I've been putting the name of the main Attendee into the "Participant Source" field just to capture the data, but this of course doesn't show up in the "Registered by" columns in reports.
Is there a hook I could use to copy that Participant Source field into the "registered by" field? Or am I missing a simpler solution?
Thanks! This is a Joomla 3.9.13 system with CiviCRM 5.18.2.
