How to Audit SSAS role permissions

A while back I was very disappointed to discover that SSAS does not have any easy way to go through all of your dimensions and cubes to see which users have access to which dimensions, cubes, etc.  Sure you can go one by one in order to get the information, but I was really just looking for an easy way to view the permissions based on individual object permissions, similar to the way you can in SSMS.  I called Microsoft and unbelievably they had no solution.  What a pinch to be in when you have an important audit coming and now it is going to take an absorbant amount of time to come up with the data the auditors are going to need.
