"Help button" & One Touch Recording

[max75]

Hoping i'm posting the right place!:
In DM7000 it would be very useful to replace the functionality of "help" button on the remote controller for instantly recording, without having to press first "video" and then "radio". The most of the times when you need fast recording it always switch on the "radio listening" instead of start recording!!
Is there anyone can help me doing that?
