Pushing information into lookup via custom action

Pushing information into lookup via custom action

I have a form called Account in which we're tracking Accounts we do business with. I also have a form called Order in which we create orders. The Account and Order forms are linked via a lookup on the Order form that links to the Account name.

On the Account report I have a custom action that will create a new order, the action does the following - 

void Order.Create()
{
    openUrl("#Form:Order", "Same window");
}

I was wondering if I can then populate the Account lookup field on the Order form with the name of the account in which I executed the Create custom action from?
