Sorting charts

Hi Navigraph team,

the automatic adding of charts is a nice feature. I figured out, when adding some other charts, that the sorting in connection with the numbering isn´t logic (for me). The automatic adding system gave me only the 20-9. I added the rest of the charts manually. So for me it makes more sense, whenn the 20-9B is behind the 20-9, as well the 21-12 … I don´t wanna talk about the 20-3 :-p ,

greets Klaus
