Hello Everyone

I need a help with the Spring Hanger topic.
I'm not an Expert in Caesar II.
Now I prepare a Instalation with a lot of Spring supports and springs.
In newest Caesar II we can choose a spring support from almost 40 manufacturers, but unfortunately I can't choose that one that I must use, becasue in Caesar II it doesn't exist.
It is Polish company with Their own springs with own spring rates and allowable forces.
So it is possible to implement my own spring support in caesar ??
With my own values of spring rates and forces and spring pre-tension ??
Thanks for Your Help
