Can thread fields define thread title?

[Sama34]

Can for example, a thread field define the thread title?

I want to add a thread field like this:

Code:

Which version this app is? 1.0 2.0 Other

---

The title must be this:

Code:

onefield: otherfield | 1.0 [otherfield]

---

Other question, if I move a thread that was wrote in a not xthread powered subforum to one that use xthreads necessary fields, what will happen? (and vice verse)

Edit:
Another one, Im using the "MyBB Parser Options" with mycode and img activated, but in "Display Format" I write:

Code:

[align=center][img]{VALUE}[/img][/align]<br/>

---

But nothing happens, it only shows the image link as a actual link :-/

Another one, when quick editing a thread, xthread fields are not show, is there a solution for this?
