Custom icons for user-created connectors

I created a custom connector for AnyTwo here in bao, and I'd like to be able to change its icon on the Connectors page, but there's no option for that. The icons seem to be fixed by the client even for connectors the user created.

My suggestion: add an option (right-click or connector page) to set a custom image icon for user-created connectors, like we can for other objects.
