Golden - IPTV - saving channels as Favourites

[Saintaholic]

Is it possible to save individual channels within a script as Favourites ?
There is a 'tab' for favs in the IPTV section.
Tabs are, customer, all and favourites.
How do you save into favourite ?.
Also is it possible to group IPTV favs with Satellite and Terrestrial channels ?
This would be incredible if possible.
