Accessing Password Protected Folders

The Registration Solution Pack has been successfully installed and works with no issues.

I have four folders in the root section of the site, one of which I want to be able to assign in the admin section for a specific user to be able to access. (four different levels of dealer pricing for products).

Once a dealer has registered, and the administrator has been notified of the registration, how can the administrator edit the individual registration file, so when the dealer clicks on the link to go to the protected page/section, the link will direct him to that folder and an index.htm page within the folder?

It would be great to have that as an edit function for the administrator for each user where the adminstrator could assign a level of access which would accomplish this.
For example, if there was an edit function on the user edit page, where the admin could select a level 1,2,3,4 and have the user directed to that directory/page it would be a snap.

Once assigned the path would be, for example, folder_1/index.htm.

Is something like this possible?
