Next, I'd like to change the value of _one_ of the custom headers each time

It appears there's no way to add/set a single custom header without clearing
all of the previously set custom headers. Is that correct?
Yes, and no.
If you stick to using the simple provided functions to build the list then
that's the only option, yes.
But you'll notice that 'struct curl_slist' is a very simply and public struct,
so when use curl_slist_append() it just builds a linked list out of such
structs. You can easily make your own functions to do the same and you can, if
you want to, just fine the single header in that list that you want to update
and update that specific node in the list between each new libcurl invocation.
Or another take would be to create a whole set of lists to begin with and then
just change between those pre-made lists while you do your requests.
It's just code. The number of options is infinite! =)
