Name files based on metadata

I would really love the ability to rename files based on metadata fields. Often times, filenames out of a scanner/app are not very descriptive and the metadata that I would assign to them would be helpful to rename the file with. This would be especially useful when exporting files. I do see related issues open for https://github.com/docspell/dsc/issues/114 and am wondering if there is any update on that? I did not post this in that thread as I think being able to rename files from the front-end to match with metadata fields would be a different issue.

Ideally, one would be able to define custom filename formats/templates based on metadata fields and choose from a list of those to have the renaming applied to the filename. These templates could then also be used when defining "sources" to automate naming.
