Domain Mapping feature request

I have a feature request for Domain Mapping. I've just started selling domains via enom and I'd love to see a few more options available to me via the Domain mapping control panel. In particular i'd love to see the following:

1) Ability to set currency
2) Ability to set payment frequency (i.e. monthly, quartely, yearly).

I'm aware that prices and payment periods are set through enom itself, however payment is still handled through the Domain mapping plugin, so surely there is a way to implement these features?
