Provide blueprint hardware request information to a workflow

Good afternoon,

I have some blueprints that allow my users to specify new disks to their virtual machines and specify configurations like sizing and mount point/Windows letter (the standard available request fields).

Now I need to pass those specific information into a vRO workflow during provisioning (the ID, capacity, mount point and so on of the added disk).

I´m working with vRO/vRA 7.0.1. I´ve created an event subscription for Virtual Machine Provisioned but I´ve tried a lot of machine properties and just couldn´t find one that´s related to the disks.

Could someone please help me out with this?

Thank you very much.
