Can I import 4 separate channels into PP from XL2
 

Hi I have an XL2 with Sennheiser EW 100 G2 wireless and PP CS3 Mac and Windows (prefer Mac) and when I import both stereo channels import as one.
I was reading about the thread about using the onboard mic and an xlr wireless and talked with canon and looked on the schematics to determine only the onboard or xlr or rca connections can be used at one time... so i connected a shotgun to the xlr replacing the onboard mic and connected xlr along with my senn receiver.
thanks
