fixed id witch several transmitters?

Hello,

I have 4 devo transmitters, i can bind them all to a moddel (not at once offcourse) if i do not set a fixed ID.
I would like to use a fixed ID, but then only the transmitter with witch i set that ID will bind. I can not bind the other transmitters anymore with that model.
Is there a possibillity to use fixed ID and use all the transmitters. (again, not at once). I vagely remember something about giving each transmitter the same number, but i can not find it again.

Thanks for any help.
Tom
