As the admin who manages our churches CCLI License reports, I'd find it useful if downloads of PDF sheet music from Elvanto could be tracked uniquely per user as this would permit us to use Elevanto to manage our churches sheet music.
Without a feature like this (or something else that supports this work flow), we are unable to legally use Elvanto to manage our music despite the ability to upload files.
Elvanto currently has support for CCLI CCL reporting but not CCLI MRL reporting. The MRL license details can be found:
A useful way to manage this is to count "unique user downloads" for each file and compare those to a stored value optionally entered by the CCLI administrator of the number of purchased copies. A report can then be generated ordered by the difference of "purchased copies - unique downloads" showing a list of PDF's for songs that have more unique downloads than purchased copies.
An example use case is given below.
If Bob, Fred and George all download a PDF of the sheet music for 10,000 reasons when they play it the first week in their band. Bob and Fred both print this PDF to use but George reads it on his iPad. The next week George downloads the same PDF again to view on his iPad again. There have been 4 total downloads of this file but 3 unique user downloads. 
I the CCLI reporter can report 3 unique copies of this PDF against the song 10,000 reasons in the Music Reproduction License as I see there are 3 unique downloads but 0 purchased copies.
The next week Alice joins the band and also downloads 10,000 reasons. The unique user downloads count will increase to 4. I the CCLI reporter can now request a MRL report which shows the PDF for 10,000 reasons have 4 unique downloads but only 3 purchased copies. I will report this extra copy to CCLI using their online tool and then set the purchased copies to 4.
I saw one other feature request similar to this one with a slightly different interface this requires more responsibility on the part of the musicians downloading the file to report the correct information:
