+First, you'll need to find the path to use for your custom level.

+For example, https://github.com/Nogg-aholic/NogsLevel/blob/master/Content/NogsLevel.umap[Nog's Level's level asset is at the content root],

+Alter the `Add-Content` instruction that adds a `GameDefaultMap` to point to the asset path of your custom level.
+Note that this requires you to use the loadLatestSave flag (since that's what causes the script to generate the ini file)
