Add Custom Object RI Section to Standard Event Object which will visible in SF1

Hi,

I have seen 'Event' is a Standard Object in SF which will support in SF1 as well.

Now my requirement is to add a Custom Object RI Section in standard Event Detail Page, which will be visible in SF1 also.

Please let me know, if the above is possible, if yes how we can achieve this.

Regards
Jansi
