Isometric Symbol for Flexible Hose

[dharunkumar.am]

Hi Guys I am trying to create iso symbol for some standard flexible hose lengths . I have two main standard flexible hoses so in iso symbols itself I need to show variation to differentiate them. 

The above images shows two different type of flexible hose routing from the main header . 
I tried many ways in iso symbols but none picks the ports and orientation correctly . can anyone give me correct procedure to get this correct , Thank you.

define once as Elbow and define once as U-bend

Thanks for your reply . Elbow for the first one seems to be working but for the second one when I defined as U-bend the symbol got disappear so I used "ELBOW-180return" block and defined as elbow and it worked .
