WebForm Customization For Submit

Hello Guys,
I have created a Webform and connect it to another doctype where webforms are being created,
when i hit the create button on webform, it create a draft copy on the doctype list…
I want those draft copies to be submitted directly, means when i hit the create button on the webform, it creates a submitted copy on the doctype list …
Any help will be highly appreciatble
