Is there a way to enable syntax highlighting in vscode-fortran-support for i90 files (intermediate files generated from ifx/ifort compiler)? and in addition even formatting for that? In other words, treat these files just as free-form f90 files.

You should use

```json
"files.associations": {
    "*.i90": "FortranFreeForm"
  },

```
