Is it possible to create a secondary discretionary disbursement sub element to Paid Leave?

Summary

There are 2 end goals we would like for the discretionary disbursement for Paid Leave so would like to have 2 discretionary disbursement sub elements. How can we set this up?

Content (please ensure you mask any confidential information):

we would like for employees to have 2 options for using their Paid leave discretionary disbursement: 1 - to cash out the money and 2 - to contribute the money to their retirement.

Currently, the Paid Leave discretionary disbursement sub element only routes to employee being paid the money. We would like to create another shadow element that is also a discretionary disbursement element that we would route to retirement. The idea is that we can use the second sub element to calculate retirement on.
