Controlling Machine Resource

Is there a way I can set the machine resources when im creating blueprints based on NetApp-FlexClone - Templates

Or will the amount of RAM always be picked up from the template ? and therefore I need a template for my normal instance (2xCPU and 3GB RAM) and another template for a Lite instance (1xCPU and 1GB RAM)

I have tried specifying a custom property: VirtualMachine.Memory.Size but it made no difference. I cant change what the blueprint states as it changes back again so presumably the template overwrites nay value?

I don't have Advanced Services either

Thanks
