Musescore 4 - New Score

Hi, In Musescore 3, when opening or creating a new score, it would put the new score in a tab next to any existing open scores.
With Musescore 4, it opens a completely new session for every score by default - Is there a way to change it, so that each score that is open, is a tab at the top of the programme, instead of having to have a session for each score that is open.

Thanking you Regards Dale
