barlines through multiple staves

Using the last version of Dorico before 2 (1.2.10…).
I have been trying to learn this thing coming from Finale and Sibelius. I like Dorico’s prints a lot and interface is nice and clean.

Some things drive me up the wall. I write many lead sheets that start out with a two or three staff rhythm or groove and then it needs to go to single staff with chords symbols later. I am able to set up two instruments (guitar & bass) so that the staves appear together but how do I make the barlines go through both staves?

Try setting the ‘Bracketing approach’ to ‘Small ensemble’ on the Brackets and Braces page of Engraving Options.
