Feature Request - web filter policy /app filter policy

can we add a feature that enable us when we try to create web policy or application policy to allow or deny some website to add automatically any relative component to it

like for example in v17.5 or any previous edition when i try to allow only gmail web site i have to add content delivery and csb to it or the site will not work will 

also the same with yahoo i have to allow the yahoo group in the application policy,

 

also if applicable to add web category for office365 and all its component so i can easy create web policy to allow it directly
