This blog post may help

In the grub2pxe Configuration section, you can see that the kernel and
"initrd" (or mfsroot) images are variable-ized (if that's a word).
Perhaps you could use a similar approach to accomplish the same.

Obviously, in that post, Grub2pxe replaced FreeBSD's pxeboot.bs and
was chained to pxelinux.
