Selecting bars not possible in Engrave mode?

Am I missing something, or do I really have to keep switching between Write Mode and Engrave Mode to first select a number of bars in the first and then be able to choose ‘Make into system’ in the other?
Or is there an easier way to do this?
Greetings, Esther

To make into system, you don’t need to select the entirety of the bars themselves. Click on the barline (or anything at the downbeat of the measure), then Ctrl- or Cmd-click the end of the selection. Then “Make into system.”

Ah, right! Thanks!
