I am using a spec where I have multiple choices for bends,pipes and other fittings in a single spec, different thicknesses and pressure classes.

And my problem is that I need to change many items, but when changing the items they always change to the first possibility in the spec.

Is the a possibility choose which choice Cadworx changes to?

Example:
I want to change a line number of a pipe, it is set at a certain thickness and when I change the line number, cadworx changes the pipe thickness to the first option of possible pipes.

The reason for this is the old spec I am using is an inhouse spec that has been changed beyond repair and I want to use a "standard" spec.

I don't want to have a zillion different specs for different thicknesses and pressure classes.
