@STLVNUB, It's done, this function has already been implemented for the next version of OC Build Wizard.
It won't be possible, at least for now, in tests carried out there was unexpected behavior of the function and I don't have time to check it.
is it just me or everyone using those configuration files having the issue with usb hdd 'the disk not ejected properly' after waking from sleep. I thought to put darkwake=8 parameter in the cmd args of the kernel, but not tried yet.
