No.  You might play around with the `test=<command>` field in the 
mailcap and see if you can use that somehow.  For example, one idea 
(untested) would be using setenv in the macro around the attachment 
opening:

macro ,a '<enter-command>setenv ATTPROGRAM foo<enter><view-mailcap><enter-command>unsetenv ATTPROGRAM<enter>'
macro ,b '<enter-command>setenv ATTPROGRAM bar<enter><view-mailcap><enter-command>unsetenv ATTPROGRAM<enter>'

And in your .mailcap

application/baz; fooprogram %s; test=test x$ATTPROGRAM = xfoo
application/baz; barprogram %s; test=test x$ATTPROGRAM = xbar
...
application/baz; defaultprogram %s

You'll have to be more specific about what you are doing and how it's 
failing.
