I'd like to name the subprocesses and then select via that name, rather than use the 1,2,3,... option.

    You are right, that would be nice

    Is there any particular use case? Or just because it is easier to track for the analyst?

    Cheers,

    Sure Martin.  Here's an example:

    I have a data set that has three categories: Math, Reading and Language Usage.  I need to do processing differently depending on which one it is.  Right now I have to create a "Selector" macro that is a large "if" statement, converting Math, Reading and Language Usage to 1,2,3 for Select Subprocess.  Furthermore, once I'm in the subprocess, the headers in each window say "Selection1" "Selection 2" and "Selection 3" rather than "Math" "Reading" "Language Usage".  I usually cheat the system and place a Set Macro operator in each window which does nothing but carry the name "Math" (hence related to my labeling request from earlier).  Here's an excerpt of something similar: 
     <operator activated="true" class="generate_macro" compatibility="6.3.000" expanded="true" height="76" name="Generate Macro (3)" width="90" x="313" y="30">
                    <list key="function_descriptions">
                      <parameter key="Test_Type_Test_Num" value="if(matches(&quot;%{Test_Type_Test}&quot;,&quot;Process&quot;),round(1),if(matches(&quot;%{Test_Type_Test}&quot;,&quot;Aspect&quot;),round(2),round(3)))"/>
                    </list>
                  </operator>
                  <operator activated="true" class="generate_macro" compatibility="6.3.000" expanded="true" height="76" name="Generate Macro (6)" width="90" x="313" y="120">
                    <list key="function_descriptions">
                      <parameter key="Selector" value="str(%{Test_Type_Test_Num})"/>
                    </list>
                  </operator>
                  <operator activated="true" class="select_subprocess" compatibility="6.3.000" expanded="true" height="76" name="Select Subprocess" width="90" x="447" y="120">
                    <parameter key="select_which" value="%{Selector}"/>
                    <parameter key="parallelize_selection_1" value="true"/>
                    <parameter key="parallelize_selection_2" value="true"/>
                    <process expanded="true">
    </operator>
    Thanks.
