Extend webinar duration while webinar is in progress

[JC64]

I've set up a webinar for 2 hours.  Is it possible to extend the duration after the webinar has started, so to add another 30 minutes for it to end at 2:30 while the webinar is still in progress?  This is for a paid webinar subscription and I am the Zoom account admin.

Appreciate any guidance.  Thanks !
