Can i use one J1 waiver to waive my home residency requirement from two J1 visas.

Hi All, 

I am a third year engineering student from a Canadian University. 
I recently completed a internship in US under J1 visa.(Subject to 2 year rule) 

I plan to do another internship in US this summer using J1 again(also subject to 2 year rule again) 
There is no government funding involved in both J1. subject due to skill list.

The question is : 
Can i use one J1 Waiver to waive the 2 year rules from both J1? (Apply the waiver after my 2nd j1 ends) 

Thanks, 
Eddy
