HTSaveLocally and then HTMLPresent.Can I?


I have a question about these converters.

I have an application,kind of a robot,wich should do the followings:
Get a HTML document - save it - get the links of that document and follow 
them - get the documents pointed by those links I got from the previous 
documents - save them - and so on....
Well, I tried to do this with registering those two converters: 
HTSaveLocally and HTMLPresent.
But the thing is that I would like those converters to called in the 
following order: first the HTSaveLocally and just after that is saved to 
call the HTMLPresent...
Can I do that? 
Or maybe this is a wrong way for what I need.
Can anyone help me out?
