Track FX risk

Guys, had an idea the other day, born out of my own need for a Findex feature, I would love to be able to track the FX risk that my portfolio is exposed to. So, when I hold the MSCI in Euros, I am exposed to Dollars as well as Euros. That would be great to track in greater detail. Or a company that is listed on the NYSE but earns significant revenue in other currencies. Maybe these are already complex scenarios.... but simply showing my asset allocation in currency risk exposure is something that I currently don’t do well and maybe Findex could help me do that.
