Ditto printing

Hello everyone. I’m trying to figure out how to convince my taz 6 and dual extruder to ditto print. I have thoroughly searched and found one thread from a few years ago where someone from lulzbot added a second extruder head but nothing about using the factory dual extruder. I called tech support but they told me it won’t work. I find it hard to believe but I am no expert. Any thoughts? I’m not against doing some creative wiring if I have to but it seems like there should be an easier way.
Thanks for any help.
