Email forwarding to Zoho Support address

Email forwarding to Zoho Support address

I'm not sure if I'm missing something obvious but how do I add an email address support@mycompany.com to forward to 
support@mycompany.zohosupport.com without using up a user licence and creating an inbox?

It's easy with other providers as the support page shows:
https://www.zoho.com/support/help/setting-up-mail-forwarding.html

Surely Zoho hosted mail should make this easier!
