@Mike Chambers Hey Mike,
Good to know! Yeah i completely forgot you can edit the templates / partials in the backoffice, its been so long since ive editted files that way I forgot it was even a thing!
Yeah the other alternative I was thinking of was creating an override for .nets default view finder and adding like a route to /Views/{ThemeName}/RestOfPath and having that be the first one try to resolve.
Could then create some little Json config to extend {ThemeName} with as many potential options as needed
