Is there a way to get clipboard and registers working separately?

[Kayzels]

In Neovim, I deliberately don't set clipboard to be the unnamed register. I'm fine with it being "+ and "*. Especially as the system clipboard is also synced through to my phone using KDE Connect, so I prefer not to add unnecessary things to it.

But with that not set in Obsidian, there is no way I can see to populate the system clipboard when I want to, and no way to distinguish between the system clipboard and the Vim clipboard.

If I do a yiw, it should copy that word. With clipboard=unnamed not set, that goes into some hidden register inside Obsidian. With it set, it populates the system clipboard.

What I would like is some way to set the system clipboard if I do "+yiw, which seemed to be mentioned before as something you could do. But this isn't populating the system clipboard, unless I set that clipboard option.

I also like putting things in different registers (some common text that would need to be pasted often). Which I would do with "ayiw, for example, to yank into the "a" register. This doesn't seem to work in Obsidian either: if I try and yank to that register, and then do a paste right after, without specifying the a register, it still pastes the yanked value that I expect to be in the a register, rather than the last yanked content that wasn't in a specific register.

Is what I'm searching for possible, or is it a limitation of either Obsidian or CodeMirror?
