Re: how close are we to having an "addAt" or "insertAt" feature?

If you’re talking about \mark \default, then I could see the benefit of that. 
The problem is, most of us overload \mark for a bunch of non \default stuff 
(e.g., ‘eyeglasses’, text instructions, etc.), because there’s no other 
mechanism available. And I doubt it would be easy to implement your suggestion 
“filtered” to only the \default marks.

But I’m always happy to be proven wrong!

Cheers,
