Update a AGOL Hosted Feature Service in ArcMap?

[TimHayes3]

I have a local File GDB with the same Feature Classes that are in an AGOL Hosted Feature Service.

In ArcGIS Desktop 10.6.1 is it possible to edit the File GDB Feature Classes and upload Feature Classes into the AGOL Hosted Feature Service? 

What I am trying to do is edit the Feature Classes in the File GDB using ArcMap, and then push these Feature Classes into the AGOL Hosted Feature Service as updates or even overwrite the Layers in the Hosted Feature Service.

if you create a weblayer and publish this to Online you will be able to update the weblayer in Pro and have the changes reflected in Online in real time
