Cross Border Expense Approval

Currently the need is claimant belongs to UK region reports to an employee in Ireland.  In this case whenever claimant raises a report for an amount say 100 GBP, the managers limit/job level should be converted to GBP and system check whether manager got approval or not and traverse his supervisor hierarchy.  Question is can we dynamically check whether the approver belongs to which Legal Entity and convert the job level/limit so that they can approve the report
