When the -LaunchWebUI is used, other parameters don't appear to have any effect, and they must be added again to the script generated by the Web UI. It would be helpful to clarify this to decrease confusion.

Example 3 shows the Path parameter with a path and filename concatenated into one string. The table of parameter definitions shows 2 different parameters: Path & Filename. Please update the example to be consistent with the functionality and parameter definition.
