Thanks for your help on this Nick. Do I understand correctly then that, if I want to have the exact same service (e.g. 'Web design') tied to 2 different revenue accounts (each in a different currency), I need to create separate instances of the service for each? For example: 'Web design (CAD)' would be tied to a Canadian dollar revenue account and 'Web design (USD)' would be tied to a US Dollar revenue account. Is that correct?
