Name screenshot using clipboard contents or other options

Thanks @Justin_Hulin @CJK for your contributions -

I am new here but plan to stay long :nerd_face:

A question: to your @CJK reply: "Just script it. After the action that takes a screenshot has saved the file, use a follow-on action to rename the file from the previous one."

I cant find any action with the name "rename" or similar. I have the same interest as @Justin_Hulin:

  1. create a screenshot of a certain area
  2. rename it to "blabla_{clipboard item}"
  3. upload to a certain folder on my FTP server

Could you please help me?

Best,
Timm
