Unable to specify destination path on runtime

[usmanibrahim74]

II was trying this solution to change the directory of backup on runtime. but this doesn't seem to work. any way we can achieve this?
#129 (comment)

there is a workaround I found which is to change the root of filesystem and setting the app name to empty string in backup.php . But I don't like it. is there any better solution?
config(['filesystems.disks.s3.root' => $tenant->id]);

return [

'backup' => [
    /*
     * The name of this application. You can use this name to monitor
     * the backups.
     */
    'name' => '',
