Save master and detail togehter

Hi folks,

I have two entities Application and Service with 1-N relationship. With original way, I can create an "Application" form and save it. Then I can add multiple service on the saved form. 

Are there any ways to create an "Application" form in which all available "Services" are list out. User can fill in the fields of "Application" form, and select multiple "Service". And finally the user click save to save "Application" form and those selected "Service"? I think it's more user friendly and don't need to break down the flow in several steps.

Thanks.
