Adding expected "hour" budget to a task

Is it possible to add a tag / filter / function that allows filtering for hours?

E.g. I have a task where I think it will require a total amount of hours of 24.0, another that requires only 3.0. I'd like to avoid adding a tag and rather prefer an additional function to add "hours expected" or something in that direction. With a function like this, I could filter for "lighter" and shorter tasks which also gives the possibility to foresee the hours needed to complete it.
