How can I avoid having to rescale linked screen shots

[Andersen, Verner Engell VEA]

All my screen shots in Framemaker are linked .png. When I write a new
version of the manual I simply replace all the changed screen shots with
with new ones with the same name and voila all screen shots in the
manual are updated.
 
Alas, when I open Framemaker they often lloks distorted and I have to
reimport or at least rescale them again. Is there a way to avoid this?

I know that I from the menu Graphics, Object properties can set the
scaling to 100% and restart scaling but I hope that there is an easier
way to handle linked graphics.
