harmony remote and Pass Labs X1

Does anyone have success programming the Harmony remotes with this preamp? As you may know it has a unique 4 button remote with toggling between modes and select functions. In other words there is no direct entry of source, volume, balance etc. The database codes don't really work and I tried the learning function but it doesn't work at all. I am using the Harmony 700 remote which is new but any experience using a universal remote with this type of unusual remote would be helpful. Thanks for your help and feedback. I know I need to call their customer service but I think my odds are better with y'all audiophiles! Thanks in advance.
