Using PD for 485 filing

Hello,

I was doing my GC process through my consulting company A. I have I-140 approved from this consulting company. With this consulting company I have EB2 filing. Here the PD is Oct 2008 under EB2.

While I did GC through the above consulting company I was working for a full time with company B. Now I have quit this company. Here my PD is Jan 9 2009 under EB3.

Presently I'm working with company C where my labor is approved. Now the question is can I use any of the above PD in company C where I'm filing under EB2 ? Since for EB2 the date moved to Jan 1 2009, I would like to use my consulting company's PD so that I become current and hence I don't have to worry about joining the consulting company ? Frankly I would like to stay in full time position with a big company where my GC goes smoother. Appreciate if anyone can reply back to me.

Thanks
