Mounting single file in docker running on windows server 2019 (error: Invalid volume specification…)

I am traing to run multiple Linux containers in Docker EE running on Windows server 2019. Everything is going well untill I mount single file to a container, like

 - c:xxxyyy.xml:/app/yyy.xml 

When I spun up an instance I receive an error like:
ERROR: for xxx Cannot create container for service s1: invalid volume specification: ‘C:Usersxxxyyy.xml:/app/yyy.xml’ invalid mount config for type “bind”: source path must be a directory

Mounting single file is possible in running Docker CE (on windows).

Is there a way get this working without to many custom workarounds?
