3dsmax, attachment with the biped rig, how do i ?

AFsoft

hi, this character is created in mixamo fuse. 

I've added an attachment to it , a bag. this character is biped rigged and now i want to add the bag to the biped rig. 
I have tried to copy the old skin modifier but the bag awfully moves with the body( in the gif ).

  how do you suggest and what are other ways to create a nice bag animation(maybe with physics capable of exporting to fbx to game engines) ?

Thanks eric. i could find some useful guides.
I have added a bone to the bag, added a link constraint to the hips. animated the bones and here is what i get now.

any suggestion to make it better ?
