[FEATURE] Copy and paste on generalization hierarchy menu

Is your feature request related to a problem? Please describe.

Hello there!

Although the generalization hierarchy wizard makes it easy to create large hierarchies, and it's pretty comprehensive regarding the types of transformations for generalization, I think it would be great to have the option of copy and pasting values directly on the menu.

This would allow more flexibility for designing smaller-size tests, to verify how different hierarchies impact utility and risk metrics. I believe all the guard-rails that protect against improper hierarchy definitions are already in-place, so there wouldn't be any overhead regarding validation of hierarchies when created through the menu.

Describe the solution you'd like

Simply allow for a copy and paste on the generalization hierarchy menu would be sufficient and allow for great flexibility.

Describe alternatives you've considered

I am also willing to implement it myself if you think that would be a good feature.
