Use a field override to specify a macro value for a radio button or checkbox field on a step:
http://www.visualbuild.com/Manual/?a...ldoverride.htm
The attached sample demonstrates this for the version setting on a Make Delphi action. A project macro VERSEL configures the default of 0 (don't change version).
This can be overriden by setting a temporary macro VERSEL value of 1 (increment) or 2 (set), which is demonstrated by the unchecked steps at the beginning of the project (you can right-click and Rebuild Selected on one of these to test). You could prompt for the value within the build or call your project from a Scheduled Task or another VBP project, etc., passing in the appropriate values.
