Disable orderconfirmation for import orders multichannel

[ESVSHOP]

Hello,

Is there a way to disable orderconfirmation for importing orders from multichannels?

We are importing orders from BOL.com (NL) and the customers shouldn't receive an order confirmation e-mail (because of different calculating prices).

There is a way if we delete this part in the code in general so nobody receives an e-mail.
Then we can make a specific status and add the order_conf. mail voor our own customers. 

but maybe there is an easier way to make this possible?

thanks,

Arjan
