Certainly.

Basically I want to avoid a situation, where diving in would result in an empty spotter:

So instead I would like to remove the dive in capability (both the icon, and the action), when the result will be empty. (And of course keep it if there will be something).

Ideally it should be possible to define it in the "parent" step, because sometimes I know there will be no further steps, and sometimes the result is simply empty (in which case I might still want to show that there are zero children).

Thanks,

Peter
