Timeline End date Automation

Hi all,

I am trying to set up an automation to make my timeline update automatically. I have already set up a dependency column that pushes dates of item timelines if i manually adjust the end date of my item timeline

But, i would like to automate this. Unfortunately i cannot select push ‘timeline end date’ by ‘1 day’. Please see screenshot below. Is there an app or integration that can automate the timeline end date if the date passes?
