Allow multiple selections of the same item in a dropdown list


Sorry if the language is confusing, but here is my example:

We are encouraging daily physical activity for our staff. Entry will happen on a Form connected to a sheet where data will be stored and modified (SUMs where "5000", "7500" or "10000" exist in @row).

The dropdown list will have 3 benchmarks for steps taken in a day, 5000 Steps, 7500 Steps, and 10000 Steps. I'd like users to be able to click "5000 Steps" multiple times to allow entry for multiple days of data.

Is this possible?
