std::format and json objects

Hello, I have a question regarding std::format.

The API works generally very well, but it is problematic to escape every
{ and }, especially when there are a lot of those, like in json objects.

Suppose I have for example the literal

"data": {
  "data 1": [
  "data 2": {"id":2,"name":"____"}
"otherstuff": {
   "void": [[1,42],[-1,____]]

And I would like to use std::format for replacing ____ with some values.

As far as I know, it is not possible to instruct std::format to use
another pair of delimiters for a single call.

Falling back to std::printf or std::cout does not seem to be the right
solution, and escaping every { and } has drawbacks too.

Was this issue ever discussed or acknowledged?
Are there some obvious workarounds I'm missing?
