AAAAK! So sorry! Totally forgot to write back. So here's what to do. Boost ALL of the four position sliders to 100%. Everything will be reversed (i.e. up is down, left is right) this is ok. Now just decrease the desired slider (remember, its reversed) horizontally and vertically until you have the box in the corner!
So if you want a box in the top right,
Boost everything to 100,
Decrease the left half way,
Decrease the bottom half way.
Hope this makes sense! Takes a little messing around, but remember, boost everything to 100, then start decreasing stuff until it matches. If you would like, I can make a little video for you to illustrate what I mean!
