regenerate missing layouts?

New to Dorico here. I recall seeing this done in a video, but I’m having trouble finding it again. When importing a midi-file, I opted not to generate layouts for every instrument, but after spending some time tidying up the score, I’ve found Dorico has done such a fantastic job interpreting the midi that now I’d like to have all the layouts. I recall there is an easy way to generate missing layouts, I just can’t find it. Thanks in advance.

Setup mode: Setup menu > Create Default Part Layouts.

Thank you!
