Log of channels watched?

[TimHare1]

Can I get, either from the X1 box, or from Customer Support, a summary of the channels that were watched during the month?   I don't necessarily need a log of dates and times for each channel, I am more interested in knowing if certain channels were watched at all.  The 'back'/history choice gives me about eight channels, not sure how to get more,  but definitely want a summary for the month.

No such log exists

OK - how big is the history of the channels that are accessed when I use the '<--' button (Last)
