Calendar Invitations: Restricting invitee auto-completion to group members

i’m admin of a user group in a nexctcloud 31 instance. the group is quiet small, but there are a lot of users on the instance and most usernames are quiet similar. that makes it quiet laborious to find other users from my group when i want to invite group members to an event in one of the group’s calendar, as many non-members also show up. it’d be therefore helpful if i could restrict the auto-completion for invitees to members of my user group.

am i understanding correctly, that this isn’t possible, as this resource explicitly mentions whole instances as pool for auto-completions:

Attendees may be other users on your Nextcloud instances, contacts in your address books and direct email addresses.

are there ways to facilitate such filter?

unfortunately you’ve not completed the Support template. Please use this when you request support

but your request seems similar to this:

thanks for the hints! i’ll delete this thread to keep the noise down. edit: okay, that’s not possible.
