Small feature request for calendar

I just switched from infcloud client to nextcloud.

What about a feature were you can set one calendar as background. For example if you have a calendar “School Holidays” then it would be nice to have these days with different background color (the user can pick) than default white.

if you select the “background” calendar and the “normal” calendar both on the left side you have a similar effect.

What do you mean? I don’t find any option like this.
