Control Page access via APPS

Hi All

I Have a question, we have  dashboard, via the create the app option. What we would like to do is to restric some page to the audience. Basically, If i have a dashboard with  6 page, but for instance I only want some audience to be able to see all the page but not page 4 or 5 as an example.

I know i can create a measure base on user principale(user login info), then create a table with the user and page they would have access, but this would not be suitable for what we want, mainly because it would be hard to manage as we have dashboard, which has multiple page and big audience, which we use security group to control.

Any recommendation!
