Select Google Calendar Event to add to list item

I would like to be able to choose an event on the linked Google calendar and add the event as a line on a list in a document. Event name would be the text and the normal !(date time) link added. – but in this case since the event was picked off a event pick list there would be no sync unless I changed the text or the date/time of the event later on. IOW – picking the event is just a starting point.

Rationale: the Agenda and NotePlan apps are interesting for their ability to add notes to calendar events. But I prefer Dynalist for note taking and don’t want to have two event-linked note taking apps pointing at the same event.

(I suppose the Powerpack might be useful for what I want, but, with respect, I’m not interested in it because its support could end in an instant.)
