update a table structure from a DS definition without using the admin console?

Hello,
I am using SmartClient Version: v9.0p_2013-11-27 in developing mode with HSQL

When I add (modify or delete) a field to a datasource (*.ds.xml file) definitions
- is there a way that the actual table structure get updated when running the web app?
- without using the admin console (import datasources option)?

thanks, Fausto
