Retain WCS info when stacking?

When stacking a few (3-5) plate solved images for better SNR (AVE Stack), I note that the WCS information seems to be lost.

I could always plate solve again, but wondered if there was a check box somewhere that would allow me to retain it?

This is for measuring faint double stars or stars with faint companions, and the WCS info is used to confirm the identity of the components.

Thanks and clear skies,
