A slightly different angle...
I would like to assign Five Live to one of the three buttons, and I understand that in theory I could search and assign as outlined above.
But... I does not 'find' the station, presumably because it is already assigned to a preset, ergo, I cannot re-assign.
So, how does one re-order those which appear in the list? Clicking and moving is not a problem, but I cannot get the station to settle anywhere.
If there is not a solution, there should be. It cannot be so difficult to program into the system.
