Default Alternative Host

Hey all, I'd like to be able to set people from my organisation as alternative hosts by default.

I often schedule meetings with myself, team members and clients.

If I am unable to attend I manually have to make a colleague an alternative host  - sometimes this can be difficult if for example, I cannot attend because I am delayed travelling. 

Is there a way I can set an alternative host by default, or even better set all users in my organisation as alternative hosts by default.

I typically schedule using 'Zoom for G Suite' in Google Calendar on chrome. 

Thanks 🙏
