How to create primary settings in one file and create another file using first file in plantuml?

Question

I have puml file like this

@startuml

'Start - This needs to be created in the 'primary.puml' file.
skinparam defaultFontName Arial
skinparam sequenceArrowThickness 2
skinparam roundcorner 20
skinparam maxMessageSize 300
skinparam ParticipantPadding 80
skinparam BoxPadding 80
skinparam defaultFontSize 12

skinparam sequence {
ArrowColor Black

LifeLineBorderColor #1A1A1A
LifeLineBackgroundColor #B3B3B3

ParticipantBorderColor #24245a
ParticipantBackgroundColor #24245a
ParticipantFontColor #A9DCDF

ActorBorderColor #4257A0
ActorBackgroundColor #4257A0
ActorFontColor Black
}

skinparam SequenceMessage {
Padding 2 
Margin  2
}
'End- This needs to be created in the 'primary.puml' file.

And inherit primary.puml file in another puml files . So, I can centralize the settings in a single location and have them applied to all other diagrams. Any changes made in the primary file will affect all associated child PlantUML files.

example :

!include primary.puml

@startuml
actor User as A 
participant UI as B  
participant DB as C
@enduml

I'm uncertain whether this can be accomplished by creating a project in Visual Studio Code and creating child files using the primary file. Please let me know if this can be achieved ?
