Apply same change to many objects in HFSS

Hi, I'd like to know how to apply the same change to many objects in HFSS (I'm using v9.0). I'm thinking about something like the Edit-> Arrange -> Offset but more powerful.

For instance, let's say I have a bunch of 3D cones, and I'd like to double their flare angle, not all of the cones have the same angle, so I can′t use the same variable for all.
Is there any way to apply this change to all of the cones at the same time?

It would save me a lot of time in the drawing process.

Best Regards

It may be too late on your current model but building your 3D structures parametrically gives you a great deal of flexibility when you later desire to make changes.

You can also sometimes make use of scripts to make changes more efficiently.
