Yes, it can be done. Page 20 of Outlaw's 886 guide says the following:
Our last stop in the Input/Output Assign menu is Analog Input. This sub-menu addresses two unique analog audio connections: the multichannel analog connection, and the balanced stereo analog connection. The multichannel analog connection can be assigned to any input except the tuner. For inputs that have a digital connection assigned to them as well, the PR-SC886 will use the digital connection first but will allow the user to switch to the analog input using the AUDIO SEL button near the bottom of the remote.
I did the exact same thing with the BDP-83 and BDP-80 when beta testing them through the Onkyo 885.
