Recovery media - auto connect to ftp

Hi,

all my backups are stored on a ftp server in my network. I have to recover my computers quite often as I run different operating systems and configurations on the same machines (virtual machines / dual boot don't work sufficiently in my environment).

Whenever I boot my machines with the True Image USB pendrive I have to enter IP, username and password for the ftp connection (could do anonymous login but I don't like that). Is it possible to set these options automatically? So that the recovery media boots with a connected ftp server? If not, is it possible to do so with a windows or samba network share?

I checked the boot parameters in the kb article but as far as I can see it's only kernel options like changing graphics and so on.
