Very often when I see a edited question made by another person, I see that the editor didn't change the wrong tag, for example, it's very typical that questions about high school algebra are tagged with linear algebra or abstract algebra. Other times I see that the editor hasn't added a correct tag, for example questions about Diophantine equations are only tagged with elementary-number-theory.
So, when I want to change the wrong tag(s) or add another tag(s) I find that I can't because it's not possible to just change tags without making any corrections on the question itself.
Since I think that it's very important that questions are correctly tagged, my question is: is there a way to change or add just only tags?
