i search for it, i think there wars an way but.. anyway.

it would be nice if we could change the name of an existing instance of a Dialog.
example:
Code:
dialog test {
  title "test"
  size -1 -1 100 100 
  option dbu
  button "test", 1, 2 2 30 30, cancel
}
alias test {
  if ($1) {
    dialog $+(test.,$1) test
  }
}
on *:something_happend:{
  // here is an reason to rename the dialog
}

i think, a well known way to create multiple instances of an dialog, is just to add an $nick or $chan to the dialog name. But for instance, you named it with an $nick. What if $nick changes his nick and you try to find the dialog with $dialog($+(test.,$nick)). You didn't find anythink.

My Suggestion: someting like /renwin for dialogs.
