Rize overall needs better batch update/write support

Overall the app needs better support for bulk updating/write. For example:

1. In the calendar activity log, I needed to bulk update various websites to the same category, and had to painstakingly do it 1×1

   

2. Same goes for the Activity → Event Log tab.

3. In the Tracking Rules setting page

4. In the Categories setting page

5. Someone posted this elsewhere, but being able to drag an area in the calendar/timeline view to select all items in that category
