Physic asset on APEX clothing

so , i trying to use new feature of 4.16 system, clothing.
its work FANTASTIC! awesome!

and i d want to use this little bit diffirence way.
when we adding clothing assets in mesh editor, we can choose colision assets, and name, etc…
seems like by clicking assets, will make directly copy of same assets.
am i right?
because when i tryin to scale up original physic asset, cloth isnt effect at all.
i want to see cloth isnt fit, if i scale up physic assets, its seems maybe falling off, or maybe clipping.

[link text][this is my currently status]
as above u tube, i did scale down original physic assets
but cloth isnt effect scaled value, so i guess clothing make copy of selected physic assets, not refrencing.

can i make clothing colision to refrence selected physic assets?
Thanks. and sorry for lame english
