Icons appending with Rig?

So I made a rig for a character, and I used the make a 3D curve as the custom bone icon. I got it all to work, however I face a problem. When I want to import my rig into a new scene, append it, all the icons I used as reference for the bones spawns to where I added them in the original 3D scene, if I delete the icons the bones custom icon is removed. In order to combat this, I round up all the icons under a collection and hide it from the viewport. But when I append the rig into a new scene the collection unwraps itself. Yes, I can do it again, but its unprofessional. How can I make a rig without the icons from showing up?
