Enforce referential integrity with Transformation

So I have a set of data that I need to insert into 2 tables, lets say user and employee - I need to insert into employee first to get an employee id then use that employee id to insert the user.  the dataset does have a unique identifier which I will be using to join with the employee after I do the insertion and obtain the employee id.  I can do this in 2 transformation but was wondering if there is a way to make it in one.  Something this    

This can be easily achieved by using a Data buffer transformation object
