Jazz lead sheets: Double left barline to demarcate a section at beginning of staff

I’m making a jazz lead sheet. I’d like to be able to have a double right barline at the end of the system in Measure 8, accompanied by a double left barline at the beginning of the next system in Measure 9. This is a standard Real Book/Jazz Lead Sheet format. The format also omits key signatures and clefs at the beginning of systems. The “B” and “C” sections in a 32-measure AABC form often have this closing and opening double bar, for instance the jazz standard “Autumn Leaves.”

There doesn’t seem to be a way to change the left barline at the beginning of a system in Dorico. You can hide the clefs and key signatures, and show the barline - but it is ALWAYS a single barline. Am I missing something?

I think this workaround is the best option I know of to create that look.

Thanks so much! I saw that solution in the thread from 2 years ago - and it’ll create the look for sure. It’s a good workaround, but I was hoping Dorico had addressed the programming oversight since that was posted.
