How do you handle multiple currencies in Service items?

We are a multinational company and are primarily using € and NOK (some US$) towards our customers. How can you handle this for service items in the Service Catalog?

As we at the same time also have the challenge that Service Catalog do not support languages our initital go was to make each Service item in one version for each language, but as far as we have found you can not set the Currency on service item level.

Any suggestions, experience in how to handle this? (We are running in MSP mode with one Portal as our customers typically have several applications and in different segments)
