Sent address from Workflow Alerts

Sent address from Workflow Alerts

Is there any way to set the FROM address in workflow alerts?

At the moment they are sent from notifications=zohocrm.com@notifications.zohocrm.com on behalf of notifications@zohocrm.com but ideally i would like them to come from alerts@companydomain.com.

I've read the CRM Workflow Alerts help page and it shows the option of setting a "From" address, but when i follow the instructions i'm never given the option to set a FROM address at the stage where is suggests i can.

Any ideas?
