I want to make custom changes to the lightning edit page. Is this possible?
I want to put a look up field to a junction object on the edit page. My developer brain goes straight to "is there a lightning component I can update?" but I am not finding the page nor is there a reference to the page name in the URL. So perhaps there is a declarative way to update?
or maybe it is not possible at all and I would have to overwrite the entire edit page.
