Hi Mark! So glad you enjoyed the post and find it valuable!

In answer to your question, and looking at the way it appears you want to set up your workflow, I think the thing that I would do is either set up a specific tag hierarchy or even a new notebook that is used just for your recurring meetings. This could also be an extension of the file folder concept, just with something more specific than the alphabet.

Another option, that may be more inline with the GTD way of thinking, is to set up the recurring meetings as projects. In the GTD way of thinking, anything that has more than one action is a project, and it seems to me that you may be able to boil each recurring meeting down into the project mindset, with accompanying notes and actions. If you need to be able to see all elements at a glance, you can use this concept with the addition of the file folder idea above.

Hope this helps!
