Assembly mates when weldment body changed.

is there a way to have SW recreate the mate if a body in a weldment part is altered?

I have a base plate and the material size is being changed.
If I alter the part by editing the weldment feature, SW 'loses' the faces and the relevant mates in the assembly go red.

One way is to manually adjust everything but this goes against the grain abit.
