I have a subordinate UDF that creates a set of features including an extrusion.  
One of the extrusion dimensions is set as a variable dimension in the UDF and has a prompt assigned.   When the UDF is inserted, user is not prompted for the dimension.  instead, the existing value is used.

If you use the following procedure (note step #6) are you able to assign the variable dim?

2.Click Model >  User-Defined Feature. The Open dialog box opens.
3.Select the created UDF group file and click Open. The Insert User-Defined Feature dialog box opens.
4.Click OK. The User Defined Feature Placement dialog box opens to the Placement tab.
5.Define placement references and click Variables.
6.Select a variable type of from the Variables list, or select All (default) to view all variables.
7.Select a variable from the Variables table, enter a new value in the Value column, and press ENTER. The Value field is updated. Repeat this step for all the variables you want to change.
8.Click  to confirm the group placement.
