I'm requesting the ability to copy a form to the same page as the source form. This is not possible today. Sometimes we want to duplicate an existing form, to the same page as the source form, so we may modify it from there (use it as a template instead of configuring a fresh form, display rules, record rules, and all).
We need to filter available values in drop downs displayed on forms depending on a variety of factors. While filter rules exist, sometimes they are not robust enough to meet our app specs. When this occurs, I duplicate the form on a page and configure page rules to determine which form should display (by hiding forms that should not display based on our page rules). With this step we're able to expose only the values we want available in drop down boxes (every time) by configuring unique filters on drop-downs displayed on each of the similar forms..
