One Note with Multiple Bookmark Groups

I’ve been fiddling with ways to put a single note into multiple locations and the only two ways I can figure to do it is by having an “index note” that I simply link to other notes from or by using tags which can get sloppy quickly. But then the bookmark feature came out and I let it sit without trying it. Well, I started looking at it today and was finding it useful, until, once again, I seem to not be able to add a single note to multiple bookmark groups. Maybe I’m missing something and if so, I would be grateful if someone could point out a workaround. It would be so nice if I could create a project bookmark group, bookmark the individual notes in this one and in others, and then when I’m done create a single note linking to those or just delete the group without losing my notes or having to rearrange everything. Thanks!
