Expenses Approvals Escalation_Expiration settings

Hi All, Good Day!

We have a requirement in Expense Approval flow Escalation should be done based on COE/Head of the Departments and normal escalation process. Currently we are using the Static Duration (7days), however we need to extend this Duration separately for COE/Head of Depts (14 Days) and Normal escalation (7 Days). Please let us know if any one worked on same scenarios in your current project or past experience.

Thanks in advance for your suggestions.
