Need Macro Article Spinner

Hey guys I am looking for an article mixer/spinner that works off of macro articles..

For example the old craigslist software craygo had an awesome program for varying ads that I would like something similar again...

For example

I (walked/strolled/jogged/ran/drove) to the (store/park/gym/bank) on (Saturday/Sunday/Wednesday/Thursday).

I would like something that I can make one macro article and spin it into20 or 30 or 40 more articles...any ideas? Any programs use this type of format where I can write one macro article and spin it?

have a look at this one -- first file attached to the OP's post
