Copy Triggers/Inputs and Outputs when creating Variations

When Variations are currently created, there is no option to copy across the Triggers/Inputs and Outputs - these have to be added manually for each new Variation (even if the triggers are the same as the original process).

It would be really useful to have the Show/Hide Comparison button available on the Triggers/Inputs and Outputs editting screens so that any details that need to be copied across can be done in the same way as copying the activities.
