Duplicating Transforms

Hello,

My 2D character snaps to position on the ledge by coming into contact with a layermask named 'SnapCheck' which works pretty well.

The problem is when I drag the snapCheck(transform) onto the character as part of the script in the inspector, Unity only sees that one transform, even if there are duplications of it.

So when I click on the transform in the characters script it highlights in yellow in the hierarchy. How do I get it so that when I click on the transform it will highlight all of my snapCheck(transforms) in yellow?

Can someone help me with this please?
