How to set a skeletal mesh as an inherited mesh?

Hi guys!

So, here’s my problem. I’ve found several tutorials explaining how to do to change only one Morph Target to scale an entire equipment on a character. But the problem is all of these were using inherited meshes, and I don’t how to set them, cause I’d like to set only the arm musculature with a Morph Target and, as a result, gloves, bracelets and everything that’s attached to the said arm fits to the arm. So my question is how do I set my items as inherited meshes of my character?
