How Can I Globally Use ISO C++ 20 for all new projects

Hi I'm wondering if there is a way to globally apply dialect to my project so it works for all new projects. As a mac user I have issues with red squiggly lines under my code that aren't errors and I have to update this on new files is there a way to globally update it to for example

I'm sorry that I don't know of anyway to do this. Perhaps some of the committers/contributors who are more expert in Managed Build have some comment they can make on this?

A new managed build project will use the default tool settings provided by the XML toolchain description of the user-selected toolchain. It would be necessary to create a new project template to override these defaults. Unfortunately this requires code. It is not something that can be configured via workspace preferences.
