Change DMX by channel change


So let’s say I have some lights in my rehearsal room and I program DMX for it. Let’s say this set of lights have Channel 1 for intensity, Channel 2 for Red and so on. These are all seven channel mode lights.
Let’s say now I go to a venue that has a different destination and channel modes on their par lights. Is there an easy way to switch?

Also, please recommend some DMX interfaces for 3pin and 5pin DMX.
