Linked Generators can be used to create a random substring containing a specified number of characters from a list of strings. The following Generators will need to be linked as part of the Attribute's configuration: 

ListGen : Contains the list of strings. 

StringLengthGen : Evaluates the length of each string in the list. 

EvalCaseGen : Evaluate if the string is less than specified substring length.

PadGen : Pads the substring with blank when it is less than specified length. 

SubstringGen : Used to substring the padded strings. 

StringReplacementGen : Trims the generated substring from the given string.
