Prompt and segments

Hi how are things. Three queries:

  1. I am going to reformulate the segments and I wanted to know if I delete a segment, where are those users registered? And if I delete, for example, “segment 1” and then redeploy it to “segment 1”, do those users return to that segment or do they stay in general?
  2. Can already published segments be reordered alphabetically?
  3. Can submenus be made in the prompt? Example: In “Zone 1” there are three options; in “Zone 2” there are two options and so on.
