title: Display dialog box only once and apply setting for the whole batch of images
body: <p>I wrote a simple jsx script, which displays a dialog box containing a list of checkboxes and 'Continue' button, which on click executes various commands depending on which items from the list were ticked.</p>
  
  <p>As this script is supposed to be part of an Action Set, I created an action which just executes this script.</p>
  
  <p>When I run the command File > Automate > Batch > The above action on a Folder or opened files, the dialog box shows for every image from the batch. </p>
  
  <p>Is there any way to show this dialog box only once and apply all its settings to the whole batch?</p>
