As Tim mentioned, you could use -estadd- to add the standardized factor
change coefficients and then tabulate the results using -estout-
(unfortunately, there is not -estadd- function to add percent change
coefficients; but see below). You would need to install the following

 . ssc install estout
 . ssc install estadd
 . ssc install estadd_plus

and then type something like

 . logit ....
 . estadd ebsd  
 . estout, cells(ebsd) drop(_cons)

("ebsd" stands for exp(b*sd), i.e. the standardized factor change

Note that some time ago Scott Long and I started revising -spost-
(-listcoef-, -prchange-, -fitstat-) and writing specific -estadd-
functions in order to tabulate -spost- results in -estout-. Two thirds
of the work are done, I'd say....

Furthermore, note that I just finished revising -estadd- and writing an
easy-to-use wrapper for -estout-. The wrapper is called -esta- and
produces publication-style tables without much typing. Furthermore, I
wrote a tool called -esto- to simplify storing estimates. You may expect
the new programs sometime next week.
