Ignore this; I hadn't noticed this wasn't the forum I was expecting... the info below applies to my T2.
You can get a single page per channel view by clicking on the channel name in the grid EPG.
What I do is to bring up the grid ( I have "Grid" as my default Now/Next style, and "Standard" as the single-channel style).
Then, for each channel I'm interested in, I "open in new tab" on the channel name. on Linux you would do that with a middle-click, on the Mac with Cmd-click. I don't know how to do it on Windows browsers.
I end up with lots of tabs, one per channel, which I then go through each in turn.
