Setting 100% width

[mrtimdog]

Is it possible to make package widths fill their bounding space, eg. enclosing package?

For example, could packages 1 and 2 fill the page width and package 2.1 and 2.2 fill the width of package 2 from the example below?

@startuml

package "Package 1" {

    storage p1s1 [
    Package Storage 1
    ]

}

package "Package 2" {

    package "Package 2.1" {
    
        storage p21s1  [
        Package 2.1 Storage 1
        ]
    
    }
    
    package "Package 2.2" {
    
        storage p22s1  [
        Package 2.2 Storage 1
        ]

        storage p22s2  [
        Package 2.2 Storage 2
        ]
    
    }

}

p1s1 <--> p21s1

p21s1 <--> p22s1
p21s1 <--> p22s2
