Changing the default SQL Server backup folder, using SSMS Facet

I found out that I cannot input a file share location during SQL Server 2014 installation, under Database Engine Configuration -> Data Directories tab -> Backup directory (I could do it in 2008 for sure)
e.g. \\fileserver\sql_backup

Therefore I had to input a local Backup path, and change the setting after install

I always thought I had to hack the registry (something like changing the key value in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQLServer, value: BackupDirectory)

But instead there's an easier way, by using SSMS -> right-click and choose "Facet"
