Ability to Pin or Prioritize Items in Calendar View

Description

I’d like to suggest adding a feature to Calendar View that lets users control the order of items on a given date. For example, being able to pin key items (like holidays or important observances) so they always appear at the top, above other events such as promotions or campaigns.

What are you trying to achieve

This would make it easier for teams to highlight important dates and improve planning, especially when multiple items overlap.
