Hello,I have couple of questions regarding DPS.We want to update our previously published app with DPS2015. Therefore we'd like to use the previously published issues with older menu selection and capabilities because they were prepared for that. if we bring a folio published with an older version of DPS into an app made with DPS 2015--> can we use this content with older version Dps menu (including content menu, birds eye view etc) is there a way to delete content within an app made with new DP...
