Creating New GL Balancing Segment and Linking to Payroll

 Hi

We are in the process of creating a new balancing segment in our GL and would like to have payroll costs relating to about 80-100 employees mapped to this new balancing segment.

I have been advised that we may need to consider setting up a new payroll but I am hoping that there is a simpler solution. 

What other options do we have instead of setting up a new payroll?

Many thanks
