How does one do this?

I have the 880, and have successfully taught "Unit code-ON" and "Unit code-OFF" raw IR commands to it using a sequence from another universal remote. I did it this way because it was before I had the capability to set up sequences on the 880.

The IR543 works flawlessly with the commands... 1-On, 1-Off, 2-On, 2-Off, etc, all the way up to 16. If someone lets me know how to upload these to the Logitech DB, I will (if it hasn't already been done).
