title: VSCode extension use multi step input directly
body: <p>I want to use the multi step input directly, for example user choose 
  F1 - and start the steps to choose items.</p>
  
  <p>Currently I found the following example, and remove the quickOpen and basic input</p>
  
  <p><a href="https://github.com/microsoft/vscode-extension-samples/blob/master/quickinput-sample/src/extension.ts" rel="nofollow noreferrer">https://github.com/microsoft/vscode-extension-samples/blob/master/quickinput-sample/src/extension.ts</a></p>
  
  <pre><code>import { window, commands, ExtensionContext } from 'vscode';
  import { multiStepInput } from './multiStepInput';
  
  export function activate(context: ExtensionContext) {
      context.subscriptions.push(commands.registerCommand('samples.quickInput', async () =&gt; {
          const options: { [key: string]: (context: ExtensionContext) =&gt; Promise&lt;void&gt; } = {
              multiStepInput,
          };
          const quickPick = window.createQuickPick();
          quickPick.items = Object.keys(options).map(label =&gt; ({ label }));
          quickPick.onDidChangeSelection(selection =&gt; {
              if (selection[0]) {
                  options[selection[0].label](context)
                      .catch(console.error);
              }
          });
          quickPick.onDidHide(() =&gt; quickPick.dispose());
          quickPick.show();
      }));
  }
  </code></pre>
  
  <p>However, when I start the extension I got the first step <strong>multiStepInput</strong> entry to choose, I want to <strong>avoid it and start directly from the options to choose resource group,(from the example)</strong>
  How can I do it? 
  I'm not able to omit the first (dummy) step when the user should choose the following, </p>
  
  <pre><code>    showQuickPick,
      showInputBox,
      multiStepInput,
      quickOpen,
  </code></pre>
  
  <p>As I directly want to use explicitly the <strong>multiStepInput</strong> and <strong>not ask to choose it</strong></p>
