Run my products in two currencies

Run my products in two currencies

Hi,
 
I know how to change the currency in Zoho CRM but I want all my pricing to be in two currencies?
 
Is that possible? If so how?
 
What I am trying to achieve is the ability to product invoices in Euro and GBP - as we have customers that deal in both currencies. Also - there will be different tax rates - I think I know how to asssign a diffent tax rate but if the person who can answer the main question can answer this - I would greatly appreciate it.
 
Naturally the question is time sensitive ;-)  I am US PST based but the business is in Ireland (Euro) and UK (GBP).
 
Please email me directly - trevor.niblock@niblockenterprises.com or on my cell 760 880 8704.
 
I will also check back here.
 
Thank you in advance for any assistance,
~Trevor
