5400 - how to add a new satellite?

[Jaroslav]

Hi, is there a possibility to add a new satellite, its tranponders, etc.?
I have Topfield 5400 (combo), it doesn't have such functionality.
I know that Vega sw from Topfield is normally used for this, but its current version doesn't support 5400 model. It works somehow, but kills all my terrestrial channels and I have to do complete reset of the box after using it (reset to factory settings)!
TopSet sw doesn't support 5400 either.

Any good idea?
