Setting up bundle pricing

[#1]

I sell tacos from our truck and they are $3 a piece. What I'd like to do is offer 4 tacos for $10 and have he POS let me choose 4 options. How can o do that?

currently, there isn't a way to have an item bundle.  you can do variation pricing on your item and add 4 of the cheaper priced ones but it has to be done by the cashier right now.

This is a needed function, and standard with most POS systems!
