How to generate 'improper clusters' by corrdump?

Alloy Theoretic Automated Toolkit (ATAT)

The cluster.out file contains all possible clusters with cut-off specified, but it only contains ‘proper clusters’ which do not include duplicate atoms. Now I want to modify some code (probably in the xtalutil.c++) to let the corrdump could generate ‘improper clusters’ like this…

How should I trick it to do this?

I guess the answer may be found around xtalutil.c++, line 426…Can any of you fully understand these codes? Thx a lot!
