Changing measure Lines mid staff

Hey everyone,

I just downloaded MuseScore a few weeks ago and I've been messing around with it. I came across an issue that I couldn't find the solution for. How do I change measure lines in the middle of my staff? Let's say I have 5 lines for my cello for measures 1 and 2, but I want measure 3 to only contain 1 line instead of the original 5, and measure 4 to go back to 5 lines.

Is this possible to do?

Thank you!
