  yes, it looked very difficult to me or else I would have
attempted it myself. ;)

  There is even more 'context' than I thought, another good
argument for it!

  Hmm, I was proposing to keep it that way unless somone
specifically used the switch in the including page in which
case they would not be confused, would they?  Did you mean
that they used the switch to get relative links, but would
not expect {$Group} and {$Name} to change?

  I guess in many cases that's true.  I have cases where a
Group.Template was used to create the initial text and
users are not expected to have to replace {$Name} with the
actual value, but it would be nice to be able to have it
set for the included page.

  If you coulde give me a head start I would try
implementing it myself, to start with I would only need to
deal with the real cases that I use such as subsitution
variables.
