Configuring local external storage as smb share

Hi this is my first post, i have nextcloudpi installed on a cuboxi 4pro with a 4tb sata drive as the main data drive. It is also accessible through smb configured through the admin interface which is awesome.

I came from owncloud 8 and the configuration wizard is awesome too.

I cant find if this is possible but it would be great if any local external storage (usb drives) could also be accessible through the smb option in nextcloud.

Is this possible ?

Kind regards Oliver
