anyone have any insight into managing advanced templates as files? i would prefer to upload a file to the file cabinet instead of copy/paste my code into the advanced template editor. is there a way to do this short of using an <#include> tag in each advanced template pointing to my files?

I think @michoel’s templates consist only of <#include> directives that point to items in the file cabinet.

I do currently, though I'm planning to switch over to SDF for advanced templates once we are upgraded to 2018.1
