Invoke built-in command from VSTS extension

Question

Is it possible to invoke a built-in VSTS command from a custom extension?

I develop an extension with customized test results tab, and I want to reuse some built-in VSTS functionality. For example invoke Create bug menu action to create a new bug work item for a given test result.
