when defining a Builder, you can also use a list of Actions for the 
"action=" parameter.
If you can get at the underlying command of the PreProcess() Builder you 
want to use, you should be able to chain all the required steps in a 
single Builder.

Before you start to implement your own text replacement Builder, you 
might want to have a look at

Does this help?
