Description

As a teacher using the Weekly Planner, I want to copy content (such as reminders or activities) from a single block and paste it into multiple blocks simultaneously.

Current Behaviour & Pain Point

Currently, I can only copy content to the same block for the next day, one day at a time. This is inefficient and time-consuming when I need to schedule the same end-of-day reminder or activity for every day of the week. A more efficient bulk-editing tool would significantly improve workflow.

Proposed Solution

Add a feature that allows users to select multiple blocks in the Weekly Planner and paste the copied content into all of them at once.
