Perhaps not of interest but, below is the Upshot of making a Template.
Shows needed files (the .png’s are not needed if not desired and their sizes can be as you prefer…).
The .HTML should be edited in editor that plays well with html (I use BBedit but many other Free editors are good).
Review of the Screenshot of HTML should clarify items to change as needed for your file.
Place the Folder in your Template directory (default or a custom location and correct Path setting).
Also, I created custom Worksheets. You might want to tweak the Default to suit your needs, too… The same Worksheet can be used for both Schematic and PCB.
