I think there are ways of doing this if you're willing to be
intrusive on the actions. For example, you could just set SEARCH on
the target and physically prepend the target path to the target name:

actions create
{
echo "hi" > $(<:D=LOCATION)
}

If you're not willing to do that, but you don't mind having it built
in the current directory, you can also add a rule in the system which
moves the target to where you want it.
