howto make spline handles symetric?

Is there a way to make spline handle symetric about a centerline? Other
than translating the coordinates manually.

Thanks

hold ctrl key
select centerline, handle(point) and opposing handle(point)
in fm select symmetric.

 

I know how to make geometry symetric, but SW will not allow (or offer) to
make spline handles symetric for me. The relation never shows up. I was
asking for an alternate method, a macro or something?

Thanks

 

I believe if you can mirror the first spline the handles will then be
symmetric.
