Using equations to change Circular Pattern

Hey guys and gals,  I ran across a CSWP practice question that had changing a Ciorcular Pattern from 8 to 10 as part of the modification from one question to another.  I know you can use an equation "table" to change angles and dimensions in a part. After changing the values in the equations you "rebuild" to make the changes active.  Is it possible to use the same procedure to change a pattern?  Or does it have to be made manually each time?

Thanks
