Is it a custom list or from a plugin (abm etc)
If you've a lot to move around, I'd suggest e-channelizer.
Use it to drag your list/bouquets from your box, edit accordingly then send it back to your receiver.
I've used it to combine services from different satellites into my standard bouquets (removing those services that are no longer available and adding alternative services from different satellites)
You may wish to disable abm if you use it as it will undo your changes if it runs in its default configuration.
