The TestStand Switching does not provide any inherent filtering capabilities. You do have a couple of options, however.
(1) NI-Switch provides the ability to set up route connections in
different groups. The Switch Page in TestStand allows you to
select Routing groups as well as specific Routes. It may be
easier for you to organize your Connections as groups and choose
between different groups.
(2) The Property page also allows you to build route connection
string and use that string for your Switching actions. It
may be easier for you to build a Route string and easily change that
string rather than selecting your routes everytime from within the
TestStand window.
Good Luck!
