It would be really helpful to be able to call the same SP more than once in a form. Also being able to enter static data should be ok when I don't want to use a variable. Otherwise I have to create a hidden default value field which bloats the form.

In this case instead of creating 3 different stored procedures to get 3 different outputs, I could upgrade the same stored procedure to output any of the 3 different results I need and simply support a single SP.
