Execute multiple APs in single invocation from C#

Looking within Zedi today I see that I can execute multiple apis in a single invocation.  There is an option within Zedi, under menu item Preferences/Options to allow that.  When I generate multiple APIs into the xml window, then execute, I see that my xml response contains multiple results, one for each API in the input command.


Unfortunately, when I switch to the "DEVELOP" window, it looks like C# only allows for sequential execution.  In my situation that is a bit of a problem.  I've experimented with ways to get the behavior I want.  If it is possible from C# I haven't been able to guess the necessary syntax, at least not yet.


Does anyone know if this is possible from C# and, if so, the necessary syntax?
