Automation for sub item status to change when another sub status has changed and dependent on the person who changes it

This is the automation I would like to create

When sub item status A is changed to done, change sub item status B to a specific status when specific user changes status A

I don’t think this can be done on monday.com but I thought I would ask.

I also tried creating it in Zapier, but I had a lot of trouble with it.
