How to attach multiple meshes with same skeleton in Unreal editor?

Hi,

I have imported a skeletal mesh in unreal engnie 4 , and I have imported all the body armours , helmets , pants , etc , as separate meshes having same skeleton structure. So when I am combining the meshes to the actor in persona using the attach mesh option(highlighted in yellow in the second pic), I am getting the desired result , but I want to attach those meshes in my game , and I am not finding an option to do that. Below are the two pictures , first one is the two separate meshes in the editor , which I want combined , and second one is the persona , which is showing the result I want.
