Bar Line Length

Greetings,

First post here. Been using MuseScore for about 6 or 8 charts now. Windows 10, v. 2.0.3. I've searched, but can't seem to find what I'm after.

In a nutshell, I wanted to mix stave styles, with most being a grand staff, and one being a lead sheet type. I can't seem to figure out how to do this without having an very tall initial bar line in the lead sheet style.

Hope that makes sense. I attached a pic and the score, hoping that's helpful.

Wondering if anyone can point me in the right direction for what I'd like to achieve.

Kind Regards,
Mike
