Myself, brother and friend have 3 adult season tickets next to each other in the West stand. Our tickets for Sunday have arrived in the post, 2 for entry by Turnstile B, 1 by Turmnstile K (at the opposite end of the ground)

.
Is there any way we can get these altered to 3 in the same end (we are not bothered which)?
If not, does anyone in a similar position have any swaps? We simply want 3 together - it can't be that hard...can it?
