Balena variables can be a single-select field

Users can make edit a variable and make it into whatever value they want. It would be better if there was an option to have fields for selection. For example, if I had a servo speed in my program “slow” and “fast” controlled by the balena variable SPEED, with acceptable values of “slow” and “fast”, someone at my company could edit this variable and change it to “1”, “faster”, “20MPH”, “bananas”.

In this sort of situation, there should be a dropdown which allows someone to choose between the acceptable balena variables “fast” and “slow” and does not allow the user to type in whatever they want.
