Is there a way to avoid writing every variable name when using gather?

I am using tall arrays and gather to extract several variables. For instance, to extract date and time I have used

   ds.VariableNames(1:2) = {'date','time'}

and then

   [date,time] = gather(tt.date,tt.time)

where tt = tall(ds). I have found a way of linking the data columns to a spreadsheet containing the variable names and the column numbers, which avoids typing

{'date','time'}

but cannot think of a way of a way to avoid typing

tt.date, tt.time, etc

What is "tt"?

Sorry, that is what I've called my tall array. I'll clarify in question.

You could use

date_and_time = gather(tt);

or

[date, time] = gather(tt.(1), tt.(2));

or if you end up with more variables in tt than you need, you can also do:

date_and_time = gather(tt(:, 1:2));

Not sure if any of these really help...
