Update ACL restricted Price List

My HikaShop products have 4 prices each - Retail, Level A, Level B and Level C

Exporting from the Products List Export button gives me a large products file where I can find the prices stored as an array?

49|34.30000|36.75000|30.38000

This would be very difficult to edit.

Is there a way to split them into separate price lists for editing then re-assemble them for import?

Or import the edited lists separately?
