So I downloaded the extension and started creating events, but I noticed the notes created appear in the general graph but are all disconnected, is there a way to make the plug in add a tag automatically to the notes it creates?

Alternatively, another way would be to add a template to all notes created or put into a folder so that the tag is inserted, is there any way to do this using any plug in?

I just want all my calendar notes to have a central connection so that they don't disperse.

Any solution is appreciated even if its different to what Im asking for as long as it links everything (or makes them all disappear from the graph)
