IntelliJ Rust unit tests default to "--release"

For any particular unit test, I can edit the run configuration to add a "--release"

However, is it possible to set this globally? I want all unit tests (via clicking the green arrow) to default with "--release"

I think it should work by tweaking the template run configuration:

But looks like the --release flag does not get propagated (which is understandable: merging template with custom config requires some messy fuzzy code). I think this should be filed as a bug, if there isn't one yet.
