Feature Request: Expanded MusicXML File Upload

Hi,

I write music on MakeMusic Cloud because I can't use the MuseScore editor. I want to upload the scores I created on MakeMusic Cloud to MuseScore Web but can't since it won't support the MusicXML files that MakeMusic exports scores as. Therefore I was wondering if MuseScore can make it to where there is an option to upload as MusicXML. I have linked an example of one of my arrangements below.

I appreciate your consideration, Issac
