Complex in/Complex out Hilbert?

[David Hagood]

I noticed that the version of GnuRadio that is released in Ubuntu 20.04 
has a real-in/Complex out Hilbert block, which is great for modulating 
SSB. But it lacks a complex-in/complex-out Hilbert for doing the 
demodulation side. Is there any package with the complex/complex form of 
the Hilbert? Or has anybody given thought to having an option in the 
Hilbert module for doing complex in?
