if you are referring to T-SQL timestamp columns: this can be done with the following, yet undocumented extension in the app.config file (which you need to enter manually, the design UI has not been implemented yet):
<extension key="db-optimistic-locking" value="backend">
<extension key="db-type" value="BIGINT" />
<extension key="db-column-name" value="vers" />
<extension key="db-length" value="8" />
In this case, vers is the name of the version column holding the timestamp value.
Please note, that this is not an official feature yet.
