***Add Prefixes in Modifier Groups***

Would be great to have the ability to add prefixes for entire modifier groups all at once. 

For example "No" "Extra" "One the side" etc. Instead of adding these one at a time in the individual modifier, we should be able to do it all at once and have the same controls as the prefixes in the individual modifiers. Such as, extra price or override price. 

It would visually look the same on the front end with prefixes showing up on the top right corner of the menu, it would also work the same way as an prefix set in the individual modifier. If an individual modifier has a set prefix, it would override the prefixes set in the modifier group for the same modifier. 

At the same time in the modifier group it should have the option to override existing prefixes for individual modifiers as well. 

This will save so much time in menu building, future price changes on the menu, and easier to operate and train merchants.
