UV co-ordinates and values.

[orbiter]

From what I can see Tools/snap allow me to adjust the size of a face to an existing picture ( I could be doing it wrong!!), I would like to would like to get 5 or 6 faces to line up or sit on the same place exactly. i.e. 5 faces to have the same UV coords e.g. 0.167 0.849, 0.167 0.849, 0.167 0.849, 0.167 0.849 and 0.167 0.849
A face is split up into 60 different Rectangles, of differing sizes but laid out as two rows of 30 .
The texture has a wood pattern ( bookcase) which is used for the top row and 6 different book spines. I need to get the 6 patterns to line up on random sized faces in a random order on the other 15 faces.
Could be done with drag and drop, zoom here zoom there .... could be better in this order....!!!

I did try exporting as a OBJ and altering it as a text file........No way

In short I would like to click on one vert, or ten verts, in the UV editor and assign a value like in "tab" on the scale menu.
