Creating order without sending E-mail

When creating an order in the Admin for a customer who eg. places an order by phone, CS always sents out an invoice directly when processing the order. I do not always want that. Sometimes the order is not yet finished or misses some info. Is there a way to prevent this and make this optional when finishing the order?

There is a checkbox allowing you to NOT send emails in your admin panel:

Home—> View orders—> Order info

Also, SWS (I believe) has a small custom mod (under 3rd party mods i believe) that customizes emails depending on the status assigned to them, allowing you to not send emails under certain conditions.

This bug also appeares when editing an order. You cannot change a persons address (for example) without letting emailing them.
