Joint Axis Settings Problem

[BrankoD]

In WF 3.0 when I use Mechanism Design and create pin connection, in Joint Axis Settings Dialog before I choose Component Zero Reference and Assembly Zero Reference, sometimes I have Make Zero option, sometimes I don`t. I have read explanation that this option is only for legacy mechanisms. This option was very useful for me. Is there any way to have this option active all the time? Or is there any idea how to simplify work without her?

When defining a Joint Axis spring, the unstretched location is assumed to be at the defined joint axis zero location.This is a good example why I need Make Zero option, correct me if I`m wrong.
