How to force rectangles layout?

Question

Is there a way to constrain rectangles layout? I would like to show memories internal organization with sectors, themselves made of banks, etc. The following code displays Sector 0 and Sector 1 in a row. Is it possible to force them to display in a column?

@startuml
rectangle "my_memory" {
 rectangle "Sector 0"
 rectangle "Sector 1"
}

I have found a solution :
rectangle "my_memory" {
 rectangle "Sector 0" as src
 rectangle "Sector 1" as tgt
 src -[hidden]> tgt  (or src -[hidden]-> tgt depending on the wanted orientation)
}
