Jorge This is my exact struggle as well. I have had to organize my entire Legend “system” around the need to compartmentalize work/personal items in Agenda Panes. I will tell you how I did it in case that helps you – but to be clear I do NOT “like” this arrangement and think I should be able to do it through the Agenda Pane configuration.
After fighting this for 4 years, I finally gave up on using Gcal-synced events and combined all my work and personal tasks into a single Document which has just two top-level branches. I named these using colored-square emoji, both because I like to use color-coding and because I will never accidentally use those characters in the text of any Task, ever.
By not using Gsync-events I can focus the Agenda Pane on a single Document and not get a bunch of noise from events in what I call “breakout projects” that aren’t part of my main, general workflows (work and personal). By putting Work and Personal in the same document I can still look for synergies between Work tasks and Personal tasks using Group-By panes that ‘see’ the whole Document.
So my two branches are “🟩 Work” and “🟫 Personal”. To focus my Agenda Panes on either Work or Personal, I apply a text filter on those emoji characters. Because of inheritance, every item under those top-level branches will “match” for the emoji in the name of its top branch. This would work without using emoji of course – just more care is needed to select a text string that has no chance of being repeated in any item (and also makes sense to you).
I reiterate though: This should NOT have to be how it’s done to get this result. Agenda Panes really should respect Zoom.
