Make it possible to programmatically end test running in CrossBrowserTesting (CBT)

Reference: SmartBear Support Case #00456278

Scenario: I would like to execute some test in a loop in the CBT environment (using scripting) against different platforms.

Problem: Every loop iteration starts new test in CBT leaving the previous test running.

Question: How to programmatically end running test in CBT?

Please find below sample code been used.
The problem is that every execution of the
Browsers.RemoteItem(...)
line of code starts a new test session in CBT. (This is fine and expected.)
How can I gracefully end the current test before the loop iteration?
I was thinking about something like
Browsers.CurrentBrowser.End()
but unfortunately only .Run() and .Navigate() methods are supported for remote browsers.

//---
function RunScalableWebInCBT()
{
  var url = Project.Variables.pvURL;
  var server = "http://hub.crossbrowsertesting.com:80/wd/hub";
  var username = Project.Variables.userName;
  var authkey = Project.Variables.authkey;

  var remotes = [
  {
    browserName: 'safari',
    version: '13',
    platform: 'Mac OSX 10.15',
    username: username,
    password: authkey
  },
  {
    browserName: 'chrome',
    deviceName: 'Nexus 9',
    username: username,
    password: authkey
  }];

  for (var i = 0; i < remotes.length; i++)
  {
    Browsers.RemoteItem(server, JSON.stringify(remotes[i])).Run(url);
    KeywordTests.Login.Run();
    KeywordTests.Logout.Run();
    // === I would like to end current test running in CBT at this point ===
  }
}
