Currency Exchange is fantastic, but needs some updates

While I'm a huge fan, I'd love to see a smoother trading system between multiple currencies. If the current price of Talisman of Sirrius is 11.5 Divines I have no option but to pay either 12 Divines (at current prices over 200 Exalts more) or convert 11 or 12 Divines into Exalts, which will cost around 600k gold.
Best fix I see is the option to use multiple currencies to complete a purchase. Let me use 11 divines and 200 exalts, or whatever's current. The conversion system is really good, but needs a 'partial amount' option.
