[vRA 7.0] [Custom email notifications] 1 email for 2 VM

Hi,

I'm using vRA 7.0 and vRO. I am currently working on sending custom email notifications whenever a service is requested.

Using the tutorial from this blog, I have suceeded to send an email whenever 1 VM is requested, activated or provisionned.

My objective right now:  Send only 1 notification for  a blueprint containing 2 VMs+. I would like something like : "hello, we confirmed your demand. Information about VM1 is ... Information about VM2 is ... (name, @ip, OS...)

My issue: the Event Broker can only pass "machine events" (machine requested/machine activated...) but do not provide "blueprint event".

Any solutions here ? I need to get all the info in one email, but the payload information are independant (2 events --> 2 called workflows).

Thanks in advance.
