Your message is not very clear: are you saying you would like to have, for FSDT airports, a more complete description of the gate selection, like we have in JFK V2 ?
But most of our airports ALREADY have them! I think only some of the smaller ones in Hawaii ( which are very easy to figure it out anyway ) and maybe KFLL, don't have it, but all the others have full descriptive terminal names in the GSX gate selection menu.
If you don't see them ( for example, KLAS, CYVR, KLAS ), check you don't have an AFCAD in conflict, or if you renamed the FSDT AFCAD. The customization is based on the AFCAD, if a different AFCAD is in use, you'll lose the whole airport customization so, on top of losing the descriptive terminal names, GSX will work there like in a default airport so, not fully optimized.
