Yes, it is possible.
Log into the station's account and create a DJ account. You're going to need it for this purpose. Restart the station after creating the DJ account, so that the new account becomes active.
After that click on Quick Links (while you're still loged in the station's account) and configure Butt by following the instructions under "Live Source Connections", more precisely the part that's under "When the autoDJ is running"
