Of course, the easiest way is to do this:

$ dd if=/blah >> /bleh

If you cannot do that, please explain why.  If you know
your reason, there might be an alternative way to do it.

$ dd if=/blah of=/bleh conv=notrunc seek=$(stat -f%z /bleh)

I suggest to write a small alias or shell function if
you need to use such commands often.  The following
shell function (for sh, zsh or bash) will do:

ddappend()
{
        dd if="$1" of="$2" conv=notrunc seek=$(stat -f%z -- "$2")
}

Then you can simply write:  $ ddappend /blah /bleh

Best regards
