Alternation and moving can be handled with conditional formulas

#+TBLFM: @>$<..@>$> = if(subvec("@1", 2, 6) == "Eval", 42, $0)

in Calc or even simpler (regex) with Lisp. Don't worry, For this I had
to cheat and look in testing/lisp/test-org-table.el with the ERTs that
should also be an advanced documentation. In this case
test-org-table/compare for the comparison and
test-org-table/copy-field for the substring.

I can not understand how with a variable if you mean that
literally. Also with macros for TBLFM as I imagine, that could be
difficult because already now there are conflicts and traps with the
TBLFM syntax.
