Any way to configure notifications per calendar (theme) on Calendar?

As it’s usual, I have more than one “calendar” – which is a confusing name, it would be better to name it after “theme” or so – on my Nextcloud account and so on Calendar app.

I have by now three calendars:

  • Personal
  • Projects
  • Birthdays

Is it possible to configure notifications for each of those calendars?
For example, I would like to be notified about Birthdays a week before, about Projects three days before and about Personal, a day before.

Is this actually possible? And if not, where should I ask for this feature? On Etar Github or on /e/ Gitlab?
