Crm 3.0: custom workflow create email from template

[wb]

Добрый день,
подскажите как создать email на основе шаблона
хочется вместо

email email = new email();
email.trackingtoken = " ";
activityparty fromparty = new activityparty();
fromparty.partyid       = new Lookup();
fromparty.partyid.type  = EntityName.systemuser.ToString();
fromparty.partyid.Value = userId;
email.from = new activityparty[] {fromparty};
activityparty toparty = new activityparty();
toparty.partyid       = new Lookup();
toparty.partyid.type  = EntityName.account.ToString();
toparty.partyid.Value = accountId;
email.to = new activityparty[] {toparty};
email.sender      = emailSender;
email.subject     = emailSubj;
email.description = emailDesc;
email.ownerid       = new Owner();
email.ownerid.type  = EntityName.systemuser.ToString();
email.ownerid.Value = userId;

Guid emailId = service.Create(email);

что-то типа

email email = new email();
email.CopyFromTemplate(templateId);
Guid emailId = service.Create(email);
