Custom poller Labels

Is there a way to query the dbo.CustomPollerLabels table with SWQL?

In the SDK I see only these Custom Poller tables:

Orion.NPM.CustomPollerAssignment

Orion.NPM.CustomPollers

Orion.NPM.CustomPollerStatus

and not the lables one.. is there a reason for that?

I would have avoided to add a custom poller for something I'm already getting as a label.

Thanks.
