Sequence Diagram: Place new participant next to the creator

Question

Is it possible to place a new participant between already created participants. For example:

 

@startuml

participant A

participant C

participant D

A -> C

C -> D

D --> C

C --> A

create B

A -> B

B -> C

C --> B

@enduml

So, in this example I want to place B between A and C. After interactions between A, C and D the participant A creates B and B should not point backwards to interact with C.

Answer 1

You can do:

@startuml
participant A
participant B
participant C
participant D
A -> C
C -> D
D --> C
C --> A
create B
A -> B
B -> C
C --> B
@enduml

Oh, I've tried this but it didn't worked. So obviously I've made a mistake in my trial. Thanks a lot!
