Is it possible to split or cut a Static Mesh in half inside Unreal?

I am curious if it is possible to remove or split in half a static mesh inside the Unreal engine? For example, I have a static mesh that is a table and I only want the legs from the table. Is there a way to split the mesh and only keep the legs? Or would I have to export this mesh into an external editor and then create a whole new texture map, etc?

I understand I could just overlap the parts of a mesh I do not want with other objects, but I cannot do that in this situation.
