title: Quartz scheduler: Register multiiple jobs under same trigger
body: <p>I'm new to the Quartz scheduler. I had few queries and hope someone give a hand here. Thanks a lot!</p>
  
  <p>First of all, let me share with you on my way to organize the jobs and triggers in single Scheduler: </p>
  
  <ol>
  <li><p>One trigger group, many triggers with unique name</p></li>
  <li><p>Many job groups, many jobs with unique name inside one group</p></li>
  <li><p>One job group may associate with one trigger so that all jobs under this group will be fired at the same time</p></li>
  </ol>
  
  <p>I think this organization is quite normal in scheduler software. However, I only found references to register same job with multiple triggers. Even though, I still thought to register many jobs with the same trigger is achievable logically.</p>
  
  <p>Following is my own logic to achieve the goal: </p>
  
  <ol>
  <li><p>Job A be created, Trigger A be created, call function scheduleJob(JobA, TriggerA) to register Job A with Scheduler firstly</p></li>
  <li><p>Job B be created, get Trigger A from Scheduler based on its unique name, call function scheduleJob(JobB, TriggerA) to register Job B with Scheduler later</p></li>
  </ol>
  
  <p>Therefore, refer to my own logic, I had two queries: </p>
  
  <ol>
  <li><p>Is it possible to implement getting Trigger A from Scheduler based on its name ?</p></li>
  <li><p>Is it a correct way to register multiple jobs with same trigger by using scheduleJob() function again and again ? </p></li>
  </ol>
