Bridge 12 downloader has less renaming options than previous versions

My download workflow includes a personal naming scheme  similar to "myID-YYYYMMDD-myBody_originalName".  This scheme is defined in de advanced pane and worked fine in previous versions of Bridge but is not possible anymore with version 12 .

How to get this back? I have not seen this limitation documented with the new release.

PS. as temporary workaround I run both version 11 and 12 side by side
