Randomize timer in automations UI (Visual Editor)

Create a possibility to easily randomize time triggers in the Automations Visual Editor:
E.g. switch off a light randomly somewhere between 22:00 and 23:30,
An option to be able to add a “random delay” action in the Action area would also work for me.
I have been able to add a random delay in YAML, but would be easier if I could just edit it in the Visual Editor
