Need some help with an F1 mapping!! LED SCREEN and some other troubles

Hi i’m mapping in a very funny way my f1, I think i’ll post the mapping since it will be finished. I’m having problems with the led screen. I want to use it to show with a letter what is the active deck.Can someone help me ? Second question: is there any way to use the f1 4 knobs to control all 4 the fx unit for instance by switching with a modifier?
Thanks

Not too sure about your first question.. I dont think the little display can display Alphabets, Only Numericals I think. However someone else should confirm this.

Question two, Yes, Its very much possible.

Can you explain me how to do thing with The fx units. The led screen show alphabets in The standard mapping by NI
