Allow setting the character for a new line

[TNAJanssen]

Hi,

We prefer 2 spaces as a line break instead of the \ because the package to render markdown on the backend.

Is there a way to configure this?

There is no way to configure this, the slash formatting is deeply entwined into the markdown parser. This is where it's converted from markdown -> prosemirror AST:

And from Prosemirror AST -> Markdown:
