Add support for "multiple instances" display in all diagram

Question

Right now, multiple instance display is only supported in sequence diagram.

Example:

@startuml
actor Alice
collections Bob
Alice -> Bob : hello
@enduml

Is it possible to generalize this to other diagrams ?

The final goal is to better support something like http://rdmueller.github.io/plantUML-revisited/

Answer 1

With last beta http://beta.plantuml.net/plantuml.jar

You can now have:

@startuml
database foo1
cloud foo2
collections foo3
@enduml
