Years of memberships

Does anyone know how to pull the number of years the members in a membership level have had membership (including memberships given as a benefit of sponsorship and non-consecutive years of membership)? 

Our organization would like to print a listing of members of our highest level of membership and group them by the number of years they have had a membership at that level.  In the past, this was done manually and took several days to complete.  Has anyone attempted this successfully in Tess?
