Well I sorta made a workaround for that :p
I just use the foldername as an description object.
Which then makes ALL pictures have the same description
But it depends on the situation if that is or is not handy
But only if you USE SUBFOLDERS like I myself do.
Otherwise it wouldn't work.
Short term solution :
Use a directory printing tool.
And a batch replace tool to create a corresponding folderdata.xml.
Long term solution :
A function in imagevue which lets you select multiple items and applying a description.
