Change Answer Field in Follow-up

In the ticketing system, when adding a follow-up to a ticket, you can choose the type of response you wish to use (Create a Task, Add a solution, add a document, ask for validation, etc.). Once you make your selection, you are 'locked' into the choice essentially and if you wish to change your type of response, especially if you have already typed out your reply, you have to copy the text, close the response, select the new response, and paste your reply.

Is there a way to make the choices interchangeable from any category without having to delete what you have you done? The way I have envisioned it is similar to internet tabs. You select the tab you want at the top of your response page and the form changes based on the selection but the textbox remains static throughout without a refresh. 

I hope this makes sense....
