Its Been A While Since Formation Designer Is Out, But...

well the formation designer is out in TSW for quite a while now. And I have my frustrations with it. Not with the bugs it has (as i am sure a lot of others have said their frustrations out by now). Its the fact that a lot of the new trains since the release of formation designs aren't even fit to be used on formation designer. What I specifically mean is that for an example DTG actually used is by getting 2 Class 465 end cars and have it (pretend) to be a Class 466. Or another example where we can just place 5 different carriages of a 387 to have it pretend to be a 5 car 377. Though a lot of recent and 3rd parties made trains dont allow you do have say a separate carriage of a MU to be either used duplicated on a MU consist or removed. 3 examples being the Class 710, there is also a 5 car variant that you can possibly make by giving it an additional non powered carriage on to the consist, the Class 170 not being able to form 2 or 4 car by removing or adding a middle carriage and the Class 158, you cant create the curse consist that is having one other 158 leading coach to be place in the middle to create that cursed 3 car class 158. Can the developers make the MU trains to be functionable for formation designer?

Another thing to mention is that we cant even use the EMT Class 43 HST's MK3 coaches in formation designer either. With the game currently being very heavily EMU ran, the coaching or loco hauled stock we have (and I dont count freight because i dont own any of the cargo line) in the game arent even that many apart from the only 3 MK1 variants and old BR versions of the MK2 (and to a stretch GWE's MK3) that we can use to haul railtours around to make it justifiable for formation designer, just why cant we have more coaching stock types to mess about with (at least on the UK side)? Can we have more (modern-ish) loco hauled coaching stocks.
