You ceratinly can do this using WFA and very easily too. Nothing to import/export but your requirement will be resolved.
1. Use cmdlet Get-NcCifsShareAcl to get ACLs of one share.
2. Use Set-NcCifsShareAcl to set the above obtained ACLs for the new CIFS share.
You want a working sample code for it? I can make one for you.
