Your situation may look like this:

You have a survey that has 5 different questionnaires. You have to separate the whole team into 3 different sub-teams. Each of the sub-teams will be responsible for a different set of questionnaires.

Unlike other CAPI, rtSurvey allows you to create as many teams (we call it User Role) as you want. For each team you have created, you can assign any forms to the team as you want. rtSurvey allows you to have all the data in one single space  while keeping the ability to create independent partitions for different teams.
