LPM Shift Reg ( Shifting Issues)

Hi all, 

 

 

I have read the megafuction for the LPM Shift Reg. 

 

Is it possible to set the amount of shifts you want in the shift register?  

 

I plan to implement a left shift by 6 on a shift register for my design.

Do you actually need a shift, or can you get the same benefit by just wiring differently? There's no real reason to use a shift megafunction if the shift stays constant; just wire the bits you want to the MSB, and fill the lower bits with whatever else you want.
