How to set an issue type so it can only be created through the portal?

[Ashley Honeycutt]

Is there a way to limit an issue type in a JSM project so it can only be created via the portal?

Occasionally we have users who are also agents creating issues from the "back end" of the project, which causes otherwise required information to get missed. 

I'd like to set it to something like: 

• service requests and changes can be submitted through the portal only
• sub-tasks can still be created internally

Thank you!

Hi Ashley, would it not be possible to simply make the necessary fields required when creating issues?
