2.2.2.5-3 Stacking Menu Selections

Users should be able to combine a series of selections into a single "stacked" entry.

Additional Information:
If necessary, stacked sequential entries might be separated by some character, such as a space, slash, comma, or semicolon. It would be preferable, however, if they were simply strung together without special punctuation. Computer interpretation of an unpunctuated string will require letter codes (by preference) or fixed-digit number codes for option selection.
