@AltamashShaikh I think it might be useful to add or change a test in core that uses that new possibility so we can directly see how and if it works. That might also prevent future regressions. You could for example change the custom dimension tests: https://github.com/matomo-org/matomo/blob/d7dced0928c7457f4e14fb571d897ac927b95134/plugins/CustomDimensions/tests/System/ApiTest.php#L162
