Create requestable services in vCAC

Hello folks,

So far, we have created a few blueprints to help provision VM's but I'm not sure we can create blueprints for requesting services.

Ex: a blueprint for a service such as email (for a new employee)

or   a blueprint to define small/medium/large deployment definition for the email service

Can anything like this be done in vCAC? Is the above supported OOTB or does it needs customization?

If yes, can we achieve this in Designer or does it needs the additional development kit module?

thanks for your help..
