If so, how would one do this? I'm not seeing a lot of in-depth guidance on what can and can't be set with custom project templates in ArcGIS Pro.
I found this ArcGIS Pro help tutorial online that walks you through creating a project template. Hope this helps! https://pro.arcgis.com/en/pro-app/2.8/help/projects/create-your-own-project-template.htm
