1.) Add a "Conditional steps (multiple)" item to the Prebuild section of a multiple configuration job.
2.) Use "Strings Match" as the type (don't think this matters).
3.) "Add step to condition". Select one or more steps to put under this condition.
4.) Click "Save" button and exit the job.
5.) Re-"Configure" the Job. The steps added under the multi-conditional step are now gone. No matter what I do, I am unable to add steps under the multiple conditional step.
Note: I am able to add multi-conditional steps to my project in the normal "build" location.
