Need to hide or trigger Preview comment on transition screen

Hi all,

I config a transition screen when an issue change status to Cancelled. I want to display only my custom field but the comment field is displayed as default. So

  1. Is there anyway to hide the comment field?
  2. I found a button (Preview comment) below the comment field, is there anyway to trigger this button when popup the transition screen?

Thank you! BTW, please find the photo for more info

In Data Center/Server you can set a property on the transition to disable the comment field… but it seems on Cloud this function is not implemented.

Thanks! Then is there anyway to trigger preview comment - the green arrow of my pic

JavaScript is out due to security reasons, I don’t think that’s possible.
