mirror seams layout is there something for it ?

Is there a key combo or a script, that can mirror the seams layout for a model ?
So that for example after you do a left food nail, also the right nail will be seam-ed

Select edges on one half
Ctrl+E / Mark Seam
Select / Mirror menu entry
Ctrl+E / Mark Seam

or split model in half
Add mirror modifier
mark seams
Apply modifier

thanks i im going for the ctrl+e option
