How do I add a Tempo Add-on custom field into AIO report?

[Igor Blagaič]

We are using Jira SD software to support our clients.

For each Client we need one or more accounts for a monthly bases billing of hours spent.

Tempo addon solve most of our needs in a way that we added custom fields in Tempo Worklog.

Our report need to combine incidents period, accounts, account categories, Tempo WL custom field  and customer organizations.

We could not assemble report with all our needs.

After googling we found the solution in AIO reports.

Is this possible to add Tempo WL custom fields into AIO report?

I've been attempting to do this without any luck and spent a lot of time.

Can someone help me or at least point me in to right direction.
