How to program a 2-button universal garage opener to work with two 3-button remote control opener?

I have a craftsman garage opener with two 3-button remote control openers. Just bought a...Chamberlain Universal two button clicker. I can program it ok, but when I do that it erases the programming for the older remote controls. So i can't get all of them to work at the same time. Any idea why? does it have to do with the dip switches?
