Hi Sam,
It is possible, but it's currently done via a python DRS to create new channels that are the sum of each pulse.
In the past we've provided these DRS on a case by case basis and developed each DRS collaboratively with the researchers, but at some point we'd like to make a user-interface tool to make it more straightforward. But in the short term, if you'd like to contact the iolite support email, we can help get you set up.
Kind regards,
Bence
