Question about generating an email on DevPortal when an event occurs

[#1]

Could someone answer to the following question from our customer?

According to the Apigee docs:

http://apigee.com/docs/developer-services/content/configuring-email

- Generating an email when an event occurs

the customer reported that the sample rule with the event 'Upon creation of a developer app just works fine and DevPortal sends email right after a developer app is created.

But in the case of 'app_status' with configured as;

"ON" : { 
"devconnect_developer_app_status_pending_approved" : [], 
"devconnect_developer_app_status_approved_revoked" : [], 
"devconnect_developer_app_status_pending_revoked" : [], 
"devconnect_developer_app_status_revoked_approved" : [] 
},

The email is sent out at the timing of cron job runs schedule by;

cron : Coniguration > System > Cron > 'Run cron every'

Can we configure this also as to receive the email right after the app_status is updated like 'creation of a developer app'?
