I set the "Do you want users to be able to selectively install only certain parts of your application" to no.
This works fine, as long as there is enough drive space. If it's not there is a dialog where to chose a drive with enough space. If I chose here again the same drive I get into the feature select-dialog...
In the Dialogs view, expand OutOfSpace and look at the Behavior node for the Resume button; the existing NewDialog control event opens the CustomSetup dialog box, but you can change it to point to a different one.
