Group hosts by services

Hi there!

We need to make reports with the grouping of hosts by services. I can get a list of hosts for a specific service by adding something like 5667/tcp to the request filter. But how can I get a list of all services from the report, as is done in WebUI on the Ports tab?

Or perhaps someone can suggest a more correct way to get a human-readable report with a grouping of hosts by service?
