It would be great to be able to filter one task list based on attributes of related tasks.

For example, if using ClickUp as a CRM:

List 1: tasks representing actions

List 2: tasks representing relationships

Tasks in List 1 are related to tasks in List 2 by a relationships field.

It would be helpful to be able to filter tasks in List 1 by the assignee (or other attributes) of the related task in List 2.

This would be akin to cross filters in Salesforce.
