Class assessment observations - freezing columns

I run observations in Mathematics and want to have my iDoceo on me as I walk around to see if students have achieved the outcome.

I can put the Gradebook into Fullscreen mode (two finger tap on middle of gradebook) but is there a way to freeze a column and have it the only column showing on the screen?

My thanks as always!

Hello Brett,
You can freeze a column si that it is always on sight but it won’t be shown alone
Here is a short video

Thank you!

Suggestion: It would be good to be able to freeze a column through the shortcut Column menu. I have over 100 columns and to drag the column I want into the freeze area is time-consuming.

Ideally, I would like an "Observation assessment mode" - where one column (or a few) are held frozen, all others disappear. Tablet is put into portrait so that all students are on the one page. I can then go around the class and assess that one or two columns.
