Option for a warning prompt when marking off items with more than one quantity. eg "Warning! Did you get 3 of these?!"

I know it shows the quantity to the right of the item but for whatever reason i am constantly missing it.  If not a warning, maybe the item could be highlighted on the list to draw attention to the fact that there is more than one quantity.  An option would be great so it does not affect anyone who doesn't want the extra warning.
