Timer with configurable input

i have a time helper in home assistant. The time from the helper should change my timer in node red. So, if i change the timer to 9am, the flow should be triggert at 9am. If i change the timer to 8am. the timer will start the flow the next day on 8am. It would be great that the timer has an input, so i can change the timer time through a time helper in ha, or to change the timer time inside node red. Is this possible?

You can use the blue HA time node. Check the box to repeat daily.
