Add Second Menu In Different Currency

Hi,

I would like make a second menu with exact same items as first menu but in a different currency. we have local and foreign customers and would like to give their bills in USD and not in local currency, And No conversion from local currency to USD is not preferred and i want all item to be in USD when bill is printed.

Basically using 2 POS as 1. i would like to ask if this is possible if so how?
