MDP2 cannot (currently) dynamically load and display programs, etc., from a board and populate a picker.
But you can pre-populate named ticks with fixed content to build the desired selectors. If you look at the RD2000 Manager or Jupiter X/Xm Managers, you will see samples of pickers that select via category, model, then specific tone, which sounds like what you are attempting. The Masters Class layout discusses how to build the spreadsheet you need as a first step. Then it is a matter of sorting the spreadsheet in the desired manner, then creating the links for the next level picker that points in. Then repeat for the next higher level picker.
I am not sure we have any posts discussing building the higher level pickers - this requires a MDP2 control calculation, but I can help with it once you have the basic spreadsheet set up.
