Microsoft Dynamics CRM Connector for AX

Hi,

I have a scenatio where Invoices are created in CRM, and I want to be able to send these invoices to AX. I had a look at the maps provided by AX-CRM Connector, and realised that there are maps for AX Invoices to CRM Invoices, and not the other way round. Does the Connector SDK provide me the ability to create a new map ( CRM Invoices to AX Invoice)? If yes, could you point me to a right resource for a reference? If no, other options you may want to suggest?

Thanks,

Karth
