Retaining channel numbers after deleting a channel

[pj_casanis]

Is there anyway of preserving channel numbers on ex1100usb, or a channel listing file that can be uploaded. It sorts channels alphabetically (which is fine) but when a channel is deleted, the numbers all shift up one. Also, new channel numbers are assigned when flicking from 'all channels' over to something more specific (eg 'sport').

I've set it all out once and got it working how I want. However, upon a reflash or decision to delete another channel, the channel numbers go out of sync again and shift up 1.

Is there anyway of fixing channel numbers?

eg if 101 bbc, 102 bbc2, 103, itv and I then delete channel 102, then currently 103 Itv will become 102 bbc2 (just an example, and it's the ****e channels I delete).

Any advice much welcome...
