I want to clone a ticket such that the original and the copy are identical in every way except the project name, and they remain identical if either is modified. Think of the cloned ticket as a symbolic link to the original. So, if the original ticket is ABC-123 (status: Done), and I clone it to project DEF, the new ticket is also listed as Done. If I change the summary or description for DEF, it changes the same field in ABC (or vice-versa). You might also consider this as simply assigning a new name (DEF-456) to the same underlying data fields.
Is this possible? If so, how?
