Unfortunately Limesurvey does not know the concept of "pages". You can simulate pages either with the question per question approach, or group by group approach.
If you want to have the majority of your questions on a single page and on some pages multiple questions, unfortunately you will need to create a group for every "page".
I don't see a way around this.

I thought this may be the case. It seems silly, but there you go, you can't have everything. It would be so simple for each question to have a checkbox that says "Question on a new page".
