[CentOS] Specifying different options for different " smb" type gvfs mount

Hi,

I'm trying to use smb:// URLs with gvfs-mount and/or similar desktop 
functionality to access SMB shares on different servers that support 
different protocol versions and features. With some of the servers, 
mount will fail with a default configuration, but I have been able to 
make it work by editing some of the "client" options in 
/etc/samba/smb.conf. The problem is, those changes will cause the 
operation to fail on other servers; I can't seem to find a combination 
of settings where all shares will work.

Does anyone know if there is an alternative way to specify client 
options that will apply to only specific URLs/shares, and not everything 
of SMB type? Note that I might be able to get by if I could set the "max 
protocol" individually for the different file-systems or URLs.

I known that I might use mount.cifs and related "fstab" entries as an 
alternative, but its password handling seems a lot less convenient.

I'm on a CentOS 7 system where all updates had been applied as of a few 
days ago.

Thanks,
