Simultaneously deployment of virtual machines using service bundle. How to address dialog fields to specific VM?

Hello, I’m wondering is it currently possible or would it be possible in future to provision simultaneously few vms using service bundle and address to each of them specific values provided from service dialog? As I see and understand correctly, provisioning order # corresponds to option_#_dialog_field. It would be great thing to add an extra column in service bundles which would give possibility to address custom variables for items with the same provisioning order #. It would reduce huge amount of time especially in huge service bundles. Perhaps you have solution to achieve it?
