The same functionality from Extra! does not exist in Reflection Desktop. You can edit a session file using the Visual Basic Editor tool in Reflection Desktop. The Property value you want to change is HostCommTimeout. This Property only effects the first connection. So if you have 4 backup hosts, you will have a custom shortened timeout between the first and second connection, then the default timeout for the subsequent attempts. You can contact technical support for additional assistance or if you would like to open a feature request so that Reflection Desktop works more like Extra! did.
