You can create Indexed view - add Index on the view.

As per BOL:
"An indexed view is a view that has been materialized. This means it has been computed and stored. You index a view by creating a unique clustered index on it. Indexed views dramatically improve the performance of some types of queries. Indexed views work best for queries that aggregate many rows."

If you are doing rebuild and reorg on the same tables, PLEASE have a consultant help you out! Hmm, actually have one help you anyway because you shouldn't be using Maintenance Plans for index maintenance!
