Use case question: Creating a meeting agenda from disparate to-do's

I have many individual action items that are blocked by questions I have for a senior stakeholder. I batch these questions for my weekly meeting with him.

My CURRENT system is, when I see an item that requires his input, I leave Monday.com and go to the Google doc where I keep a running agenda. But this is annoying and means I have to make updates in two places. I'd like a way to indicate an individual action on my boards, needs to be added to the agenda, and then be able to generate an agenda by rolling up all identified questions across all my to-do's across my boards.

Does anyone know of a way to do this? I've looked briefly at the meeting agenda template, but that seems to be more "create a to-do / board for a specific meeting," so if I do that, then I have to put topics in two places still (on the original to-do that spurred the question, plus the meeting-specific board).

Specific Example: I have a to-do to build out our website, but to do that I need to ask the senior stakeholder about how extensive we want our social media presence to be. So I have a to-do of "build the website" with a sub-action of "talk to senior stakeholder." How do I get "talk to senior stakeholder" easily and automatically into an agenda without having to update in multiple places?
