Organize only documents for commercial users by web app

Hi to all,
I’m looking for a feature to aggregate documentation in gitlab only for commercial users.
In our local git we have a lot of projects where we save commercial, functional, development document and source code organized.
Normally this documents can be seen by normal web navigation.
Exists some feature of git or gitlab to allow to aggregate for every project the commercial documentation to allow to a commercial user to see only commercial document without lost time to search it or navigate in a lot of projects?
Or exist some plugin to allow it ?

If somebody use git or gitlab in a company he/she can see this needs. So I’m looking to solve this type of request.
For example it can be done by a cron that aggregate the documents by tag in git but I’m looking for something ready to use with a minimum configuraiton effort.

thanks a lot for your support.
