Easy mode for my technophobe nan

Hi,
For an early xmas present for my nan, I have set up a kodi box for her..
However, she is a major technophobe.. so I’m having to put things on for her and then come back when finished to change to something else etc etc..

Initially what I’d love to be able to do is the following..
Have a favourites folder say.. where I can add a few freeview channels she likes to watch.. and then click play on one of them.. the channel starts to play. Then if she wants to change channels, she can just click one button to either go to another or cycle through them with up and down (like a normal tv that she’s used to)

Is this possible?

Many thanks & any help greatly appreciated
