Is there anyway I can override the 'Approve/Reject' button with a VF page so that when I click on the button, I'm taken to a page where I can enter custom data?
There seems to be no documentation on this and this post End of javascript sidebar workarounds? says that Javascript sidebars don't work from Winter '16.
Does this have any relevance? If not, please do help!
And this is to be done on the 'Home' tab and not in the related list
