ANSYS Workbench change many bushing stiffnes at the same time

[mojado2000]

I have a model with many bushing that have the same stiffness values (i.e X time the bearing type A and Y time the bearing type B ).
How can I change the value of the stiffness of my bushing in one time?

I wuold like to have something like a "variable" Kx_A, Ky_A, Kz_A and use this in the bushing definition, so if I change the value of Kx_A, the stiffness change for all those bushings that use Kx_A.

I don't want to "promote" as design parameter the stiffnes value because this lead me to have many design paramenters with the same value (I may have hundred of bushing).
