Add a property in a Service Blueprint

Hello!

I added a new service Blueprint, Can I add propoerties like "VirtualMachine.Network0.ProfileName" ?

How to do it please ?

The new service blueprint use a workflow I have edited on Vco ( a copy of " Clone virtual machine, no customization"), There is a way to use this workflow on a new  Blueprint under "infrastructure >> Bluprints" and add properties ??

Thank you for your answer in advance
