Repeat sections for each household member after collecting roster

Hi All,

I am developing ODK for a household survey. let me explain my problem.
there are 100 plus questions in survey questionnaire with 6 sections. 2 sections will be asked from head of the household while other 4 sections will be asked from each member of the household.
I have created household roaster. after this household roaster i have 2 section which will be asked only from Head of the household and next all sections will be asked from all members one by one.

issue is that at first i have to entered all members of the household and these all members will answer from section 3 to onward one by one. how can i start repeat section 3 to onward for each member of the household?

Thanks in advance
