Reusing components with vertical shift

Hi, I am trying to re-use the comma as a component to generate the apostrophe (quoteright) but also the quotedblright and the quotedblleft. I would like to preserve the automatic alignement. Is it possible to keep the automatic alignement and operate a vertical shit on the component ?
thanks
Seb

Keeping the automatic alignment is not possible. But using metrics keys is almost as good.
