I have a problem when inserting a design parameter with the existing set using GUI.
Even if I choose After Current option, still it creates a separate design parameter set which is very troublesome.
Howw to adress this issue other than just using Text Editor?
Make sure that a proper design code (same code as in the already created design parameters block) is selected in the Current Code list . Then select some of the already defined parameters and add a new parameter with the After Current option selected.
