Global Script Variable - Array

When creating a global script variable you have the option to define the variable type like INT, Boolean, String, Float but there is no

option to define a variable as an ARRAY. Is this be design or a miss by SAP?

I want to be able to store a list of dimension values to use it various scripts in my application without having to fetch it from

the data source and without having to create a listbox or something. Why can't you create a global variable as an array?

Thanks
