You know, you could just ask us. We're planning on adding features for a 2014 release, but until then you can navigate to C:\Users\%USERNAME%\AppData\Roaming\Autodesk\ApplicationPlugins\ and open the Create BOM folder. There will be a packagecontents.xml in there. Open that up and look for MaxVersion, which will say 19.0. Change that to 19.1, and restart Plant.
