I have 2 items: "Collection" and "Category". Both of them use the same template A which has field IsCollapse. When I create any new collection it should have the default value of true and for category it should have false. I cannot create a separate template for each of them as the website has lots of business data for both items. Is there any way other than writing custom code to have some kind of rule in Sitecore to set different values for the same field?
