Forum:DWBIT: Odd man out

When naming issues of magazines, we seem to be fairly consistent. We take a proper acronym of the magazine's title, right?
 * DWM Issue 1
 * DWA Issue 1

But then we get to Doctor Who: Battles in Time and suddenly it's
 * Doctor Who: Battles in Time Issue 1

Can anyone give a good reason why I shouldn't mass move all issues of DWBIT to the format, DWBIT Issue 1?
