Restricted options multi-select (ie. select only 2)

Being able to set up a multi-select form that has multiple options but the user is restricted to only a specific amount would be super user. Like ‘pick your top 3’ from a pool of 10 options.

Some background:
I was trying to set up a multi-select question on a form allowing a user to only select 2 of the 4 options (instead of an indeterminant amount). I thought I could use the label selection limitation to make this happen but it just defaults it back to single select.
I logged it as a bug and was told that I’d need to log it as a feature request as 'unfortunately, at the moment, limiting the ‘multi-select’ question by a custom ‘label selection’ limit is not supported. Therefore, the default behavior will go to the ‘single select’ behavior, which is the 1 label selection limit, regardless of the setting in the associated dropdown column. ’
