This function is assumed to link 2 issues, but you see, how can I link this issue to another one? It can only select "Trigger issue" which is the issue itself, very useless; or select "Most recently created issue" which is very vague. Isn't it very useless? How can I don't which one exactly it is?
It's expected we can select another issue, why don't you implement it in this kind of straightforward and easy to understand way?
