[RESOLVED] SSRS tablix - want to center a title over it

I have a tablix on my report that's a pivot table and can have a variable number of columns depending on what the stored procedure returns. Is there a way to center a title over the tablix when you don't know at design-time where the center is?

I found this that says currently no, you cannot, but that was in 2011 so maybe currently you can?
