I'm not quite sure about what you mean here by "more automated 
handling". The substitution of JINJA_TEMPLATE_SEARCHPATH takes place in 
the scanner, right? So it's part of the Tool, and the normal user 
shouldn't have to worry about these steps at all.

Can you give a short example (like in a code snippet) where you point to 
an expression and say: "I want to get rid of this, and have it look more 
like this."?
