How do I increase in rib while staying in pattern?

[knitknitter]

I'd be grateful for advice on how I can increase in rib (I am most likely going to do k2, p2 rib) while staying in pattern -- i.e. I don't want to increase from k2, p2 rib, to k4,p4 rib in the next row, I just want to incease at the sides as I am making a longer sweater and want it to fit over my hips. Thanks in advance to those who respond.

What I do is make 1 at the beginning of each side. If your row starts off with k2, p2 I would make 1 p stit
