Teamtrack : Adding Release Date

One of our requirement was to add requested release date of a application in Teamtrack.

For example suppose a appliction "ABC", now i would like to add a release date "04/04/2012".

We have a procees to login to the remote server and select the application name and add the release date

Now my question is can we add the release date in Database directly. If Yes in which all tables and which column we need to add?

Thanks in advance !!!
