Hi!
I know this is an old post, but I have the same problem a recently, so I made my own sensor file for Quick Cap 32 and I just added to Colin generic Caps as ASA 32.
It is based on ASA electrode standard positions, but contains just the Quick Cap 32 electrodes, so is like the Neuroscan label matching option. I tested it and it works fine!
You can Try it:

In order to work fine, you need to sort your electrodes in this way (this is the montage):
FP1
FP2
F7
F3
FZ
F4
F8
FT7
FC3
FCZ
FC4
FT8
T3
C3
CZ
C4
T4
TP7
CP3
CPZ
CP4
TP8
A1
T5
P3
PZ
P4
T6
A2
O1
OZ
O2
I hope it helps!
ps: you can always make your own file if you need, just take a standar position cap and delete or add (and sort) the electrodes you need.
