indexes with included columns in DAX 2009

DAX 2009. I know that it does not support include clause in create index statement. I have found potential opportunities to trick this limitation (…/trick-to-add-included-column-in-ax2009.html)..)

We are having real problems with performance and indexes would possibly solve it. So the question is: is the solution viable, are there any pros and cons besides those described in the article? Any other things to think about? Maybe more links?

I will really appreciate your answers!

Thank you in advance!
