Add Library server - standalone

Hi All,

I really need to add some shared folders full of ISO & VHDX files to my VMM environment however they resides on a server which is not a member of domain and cant be joined. Its the same server which is running the Hyper-V host. Im able to add it as a Hyper-V host (Add host from perimeter network wizard) to my VMM however Im unable to add it as a Library server.

I read that Library server can be only a server which is member of the same domain as VMM. Is there really no other way or workaround how to add these folders to VMM Library?

Thanks
