Is it possible to alter the size of the circles on the deformation bezier handles

I’m creating a leg deformation rig that that has a bone articulation set up. But I have also added a curve deformer to the shin that starts at the knee and runs to the ankle giving me the option to use bendy leg type animation and jointed leg type animation at the same time. It works fine.

My only issue is that when the deformation controls are too close to each other it gets tricky to select the one I want to use. I have to zoom right in to select the deformer I want.

Is there a way (like in 3d software) where you can create a non rendering image that is linked to the deformation control? The non rendering bit isn’t the problem its the linking I cant seem to figure out.

have you tried scaling the nodes?
