I've received a feature request to add support for adding Ribbon Customisations to a specific entity form in the Ribbon Workbench. Dynamics CRM allows you to add RibbonDiffXml to specific FormXml element so that those custom actions only apply to that form.
To-date I've not personally found much use for this and although I won't be adding this feature to the CRM2011 version, I could in the CRM2013 version.
I'd like to get an idea of how important this feature is to you - so please if you need this functionality can you vote it up at:
ribbonworkbench.uservoice.com/.../4230997-support-editing-of-form-specific-ribbon
Many Thanks!
