Icon/Image Inheritance from Parent Session

Hi,

Would it be possible to have the image for a sub-connection/template session inherit from the parent? We use custom icons in our vault pretty heavily, and we are trying to utilize templates more for similar items but have found that there is not a way currently (that I've found at least) to have the sub connection icons inherit from the parent. This is causing us to create a ton of templates and I don't think it will end up scaling well.

Thanks as always!
