Management reporter 2.0 and Additional settings Performance issue

I have found another issue whilst working on performance issues at a client and with the assistance of Microsoft have picked it up.

When setting up a company the in Management Reporter 2.0 with or without Feature Pack 1 with the following Additional Options will cause performance issues

Account Category,
User Defined 1,
User Defined 2,
User Defined 3
User Defined 4.

Also do not mark Dynamics GP Financials with Analytical Accounting. Hotfix has been released for Feature pack 1 but I can confirm if this helps with performance issues

Example of performance saving by unmarking the options is as follows for a report with a tree that contains 84 units:

With options marked: 60 minutes
Without options marked: 30 minutes
