We have rolled our a live copy from master but cancelled inheritance for many component on that page to make local edits.
Now we would like to re-lock all components(re-enable inheritance). Is there a way I can do it on single click or I have to go to each component and click on re-enable inheritance.
We do not want to loose our local edits as well.
you can try to re sync a page from master, the option is available from page properties live copy tab.
I dont think re sync will re-enable inheritance for the components for which we cancelled the inheritance to make local changes.
