It would be possible to add a new column, and filter of when the interaction ended?

On the Performance -> Interaction report ?

Our operation normally search this way, when they want to see how many sells a agent did in a given day

As we started to use the callback function it may happen that a interaction will remain opened for days, and the date/time in the report indicates only when the interation was opened, so it's giving a different information to them.

Thanks,

If you have someone with programming skills, you can also create a custom report using the Analytics portion of the PureCloud API:
