List all tickets of a user

this seems like a workaround.

i dont want to do this in search, because it would impact the performance.
how can i do it in the “users profile”:

i think doing it there would make more sense. but if it cant be done, then i guess ill have to change the limit in search.

EDIT: In the meanwhile i did the suggestion, but it had no effect. i think ill have to restart some services right? or anything else?
EDIT2: i restarted the zammad service but it had no effect at all, i even restarted the vm and it had no effect at all. it just shows 50, even though i told it 200.
