Plugin Multi Currencys

I was wondering if anybody could help with a question i have been asked

Is it possible to use multiple currencies on one jigoshop instance, is it possible to force individual products to use different currencies.

For example we are holding a event in the UK where we need to charge in GBP, but we are also hosting a event in the US which needs to be charged in USD.

I purchased the following plugin – https://www.jigoshop.com/product/jigoshop-multiple-currencies/

But i am unable to get it working the way i imagined it would.
