Rhino 8 default template when opening .obj directly

Hi,

We open all our OBJ files directly by double clicking on them inside windows file explorer and having that opening rhino 8. I want to set the default drafting text font to SLF, I have set a default template with that as the default so when we open rhino 8 that template loads, but it doesn’t load that template when we just open a OBJ directly from file explorer.

any ideas how to set this up or if its even possible.

Thank you.
