This is more of ACS side question, and hence you should try to post it to CSC's AAA community here:

ACS does has this feature to provide restricted access to users by creating such a restricted profile.
You can create Command Authorization Sets to perform this. Command authorization sets provide a central mechanism to control the authorization of each command issued on any given network device. This greatly enhances the scalability and manageability of setting authorization restrictions.
You can check Command Authorization Set here for ACS 3.2:
