[TxMt] Including values of static variables in others?

[Daryl Spitzer]

When defining "static variables" in Preferences->Advanced->Shell
Variables, is it possible to include the values of static variables in
the values of others?

For example, I tried defining:

P1     /some/path
P2     $P1/subdir

But the value of P2 is "$P1/subdir", not "/some/path/subdir" as I wish.
