Waiting room customization

I would very much like this information too. I want to set up a demo Zoom meeting as part of an online training course that runs continuosly for learners to practise logging in and out with. I would like to have a video or text in the waiting room giving them further instructions. Obviously. I don't then want to have those same instructions in every waiting room I create from that poiint onwards! 
The only work around that I can currently think of for my situation is to create a new account that is ony used for that purpose, but that's not a very good use of an account that the company I work for a paying for.
Any ideas Zoom?

Me too!  I need this feature as well.  I have 4 distinct uses for my zoom account and the waiting room customization's across uses are not compatible.

Anyone out there in zoom land know how to do this, if it's a feature request, or have a workaround that doesn't involve adding a user for each customized waiting room?

Thanks!!!

Same!  And I can't find a way to customize a watiing room.

i would love to know that too

It’s such a nuisance at every meeting! I’ve supposedly set up a waiting room, but there’s always someone who manages to join without authorisation. I’ve Googled how to set up the waiting room, but the steps aren’t listed in the menu exactly as they’re explained. Why don’t they include a clear option in the menu for each meeting to enable or disable the waiting room?
