Not possible to provide additional command line parameters for "Run Test"

[Gamadril]

When I start a test in VSCode with "Run Test" button above the test, the executed command cargo test -- --nocapture TEST_NAME fails because my Cargo.toml is not in the root folder, but in a subfolder.

root/
  ├── src/
  │   └── Cargo.toml
  ├── doc/
  ├── config/
  └── README

When I call cargo (command line or lldb launcher) I always provide the --manifest-path=src/Cargo.toml parameter. It should be possible to pass additional parameters for test execution as well.
