Plesk 12.x / Linux :: Cannot Put Cgi-bin Outside Httpdocs

Moving sites from other servers into a Plesk 12 environment (Centos 6.5) I cannot see a way to set cgi-bin in the webspace root directory instead of document root (httpdocs). In previous Plesk CGI support allowed selection of cgi-bin location.

I have tried (to no avail):

Code:
/usr/local/psa/bin/domain -u mydomain.tld -cgi-mode www-root
/usr/local/psa/admin/bin/httpdmng --reconfigure-domain mydomain.tld

Code:
mysql> SELECT * FROM dom_param WHERE dom_id=x;
(where x is the dom_id of my domain) shows the cgi_bin_mode param has val www-root but no change to system/<domain>/httpd.conf.

Relocating cgi-bin to httpdocs/cgi-bin is not an option - some of these sites are development environments where I cannot move cgi-bin on the live environment and some of the scripts use relative paths.

Is this no longer possible in Plesk 12?

The following works (oops):

Code:
/usr/local/psa/bin/domain -u mydomain.tld -cgi-mode webspace
/usr/local/psa/admin/bin/httpdmng --reconfigure-domain mydomain.tld
mkdir /var/www/vhosts/mydomain.tld/cgi-bin
chown myuser:psaserv /var/www/vhosts/mydomain.tld/cgi-bin
