There is no 'Expander' keyword to use into a Decision table.

To be able to use a DSL file into a decision table I had to modify the generated String by SpreadsheetCompiler to add the expander keyword with my DSL file into this String(at the right place), and then add package to the builder with the DSL file.
It works fine but I guess it could be done automatically with an 'Expander' keyword for example even if it's only easy String manipulation?
