Need stock ticker - map/transform the terms before tagging

Like to know if autotagger can be extended to include the following feature:

If phrases such as "International Business Machine", "Big Blue", "IBM Inc." are found with a node, then the stock ticker for the company, IBM, is tagged.

Essentially, we set up a list of texts (company names) , and their corresponding terms ( company's tickers). The autotagger module is smart enough to map them before tagging.

This feature is very similar to synonyms, so it is may be just a documentation issue.

Thanks.
