Aggregate Meter (3/4 + 1/8)

Hi,

How do I get rid of the dashed barline? Additionally, what would I need to do in order to properly notate the rests (1/4 + 1/4 + 1/4 + 1/8)? I wish this would be an automatic process …

shift-m 3/4:1/8

To show explicit rests in each bar you will have to force duration of the first quarter rest. Then you can copy this to all the bars where needed.
