[CWB] Assigning cqp queries

[Trklja, Alex]

Dear all, 

Is it possible in CQP to assign cqp queries to new variables and then re-use them or have you thought about including something along this line to Ziggurat/CWB4? Say, I have the following queries:

A= [pos='JJ'] [pos='NN']
B= [pos='MD] [pos='VV']
C=[pos='RB'] [pos='VV']

And I would like to combine them in the following two ways:
D=A+B
E=A+C

Thanks.
Alex
