How to use a set of macros (a file) in different plantuml diagrams(.pu files) without including the file?

Question

I am generating svg's by using plantuml.jar file, And I have a file where all the macros are defined and want to use it in all the plantuml diagrams(.plantuml files) with out including (!include directive).

Because I do not have write permission to modify plantuml files and also number of files are huge to modify even I can. Is there any flags to plantuml.jar file to specify the macro file to use for plantuml diagrams?

Comments

In the help I see:
      -I\path\to\*.puml   To include files with pattern
did you have a try with this? (I didn't try it)
