instead of a delay node you could use varidelay. You’ll have control over the remaining time of the timer thus allowing you to add the desired amount of extra time.
Node Red timer that will survive an HA restart, a Node Red deploy or restart. Timer goes on and it creates an entity in HA with the remaining time. The sensor does update the remaining time in lovelace.
Example for 15 minutes timer.
You will need: ‘node-red-contrib-stoptimer-varidelay’
