It is trivially easy to copy CDs to a USB hard drive, after which you can use the feature in the latest firmware to create playlists. Give that a try and see if it does what you need.
The OPPO has a much richer user interface than any CD player -- way more stuff to deal with. To get to that stuff requires a display at the moment. OPPO has said it is working on enhanced IP (home network) control protocols for the 103/105 which may enable you to do the stuff you want without a display, but those are not available yet. (What's available at the moment duplicates what you can do already with the remote control, and no more.)
