Adding repository

[Jyang772]

Is it possible to add a repository with default disabled?

@ <RepositoryUpdate>
<Repository action="add" url="http://www.example.com/repository" name="user" password="password"
displayname="Example Repository" />
</RepositoryUpdate>@

I have tried adding:
@
<Enabled>0</Enabled>
@

but the repository is still being checked in the installer settings.
