Transposing score

New to Dorico so my apologies for a probably simple question. To help me learn Dorico I’m just trying to copy an existing orchestra score.

I searched for this and couldn’t find a straightforward way to make the score a transposing one. In Sibelius when you create an orchestra score you have a button to click that makes it a transposing score.

Where is this option in Dorico?

Thank you in advance.

It’s in the Edit menu: choose Edit > Transposed Pitch or Edit > Concert Pitch.

Just what I was looking for. Thanks.

You can also go into Preferences - Key Commands and under the ‘Edit’ section you will find ‘Layout Transposition’ there and you can assign your own key shortcut. I used Cmd;OptT for transposed and Cmd;OptC for concert pitch.
