How can I upload Multiple Expense Approval rules in BPM?

we have a requirement for Hospital case scenarios where each expense report must be routed to the respective hospital CEO for approval. Given that we have approximately 160 hospital CEO positions, this necessitates the creation of around 160 individual rules based on cost centers for each expense template. Currently, we have two expense templates in use.

As there is no available functionality to upload approval rules via a spreadsheet in the BPM system for expenses, this configuration must be performed manually.

Could you please advise if there is any alternative workaround or solution that could streamline this process?
