Late-time ISW in camb

[Hidde T Jense]

Following this paper, I want to disable the late-time ISW in camb and then add it back into the CMB as the template described in the paper.

Is there a way to remove the late-time ISW easily, or would it require changing the fortran code, and if so, where can I find the inclusion of the ISW that allows for this modification?

For completeness, I looked through the fortran code and found this, but removing the ISW term from this line does not give the expected result (which I presume might be because I am removing all ISW and not just the late-time term?).
