Roster interest in repeat visit

Hi, dear all
I am currently designing a follow-up questionnaire to monitor the administration of a product over a 20-day period. Each day, the same questionnaire is administered, and I’ve included a “Day” variable to capture the specific day of administration.

I’m wondering whether it would be useful to use a roster in this case. What added value would it bring?

From what I’ve observed, using a roster simply replicates the timepoints within the CAPI interface. Does that mean that the same CAPI instance would be used throughout the 20 days in a daily synchronization–resend scenario?

Wouldn’t it be simpler to create 20 separate CAPI assignments (without using a roster), where the only difference is the selected visit day?
