dynamic value Google Analytics

Hello, first of all thanks for the plugin but I have some problems on version 14.
The project will be used in different sites so
@enablegoogleanalytics(value = “xxxxyyyy”)
I was unable to put this annotation value from outside(inject). I am having trouble because everyone’s google analytics value is different. So is there anyway to make it dynamic?
Do you have any suggestions?
