showing extracted parts in the workspace

Hi,

I used a feature in musescore =<3.6 where the extracted parts also appeared in the session workspace (not sure of the word), showing as tabs along the top edge, next to the 'full' score.

Each part tab was fully editable, and printable, and updated the 'full' score on the fly, and vice versa.

Really useful feature, esp., with dense or complex parts.

Does this feature appear in MS 4.2, and how is it accessed?

Kindest
