However, only _two_ of them can be active at the same time, controlled by "set AnchorNumberTarget …" and "set AnchorNumberKeyword …".  By re-running the same query several times with different settings of these options, you can build a table with the positions of all markers.

If you want to work with queries with more than two marked positions and 
you're familiar with python, you might want to use the cwb-ccc package, 
which you can install via pip from PyPI (https://pypi.org/project/cwb-ccc/):

    pip install cwb-ccc

Have a look at the df_anchor_from_query() method from ccc.cwb.CWBEngine 
to directly work with corpus positions.

Best,

Philipp
