Focus on context - possible


I want to create a perspective where I can see all the remaining tasks that are delegated to others. Currently I have a context group “delegated” and within that all the people I delegate to. Moving the tasks out of their respective project is not really an option. Making the delegated group on-hold then filtering for on-hold items is again a route I don’t want to walk down on.
It can be solved on my mac with sidebar selection but that doesn’t work when I use the context on my phone / iPad.

Any idea?
