How can I put the channel number on OSD?

Firstly thank you for this fantastic skin maker, and sorry for my poor English.

Eminence is the most perfect skin of KODI, but I wanna little mod to this skin

When I changed TV channel, I can see program name, channel provider, clock, weather and many information,
but it hasn’t channel number. I wanna put channel number with EPG program name for my old parents, which one xml can I edit?
I look for many xmls in 16×9 folder but I didn’t know that

Thank you very much
