How can I quickly track cash added or removed from multiple tills?

I have discovered that the majority of the tie-out issues with the Finance Summary are related to the inability of Shopify to properly handle a ‘partial refund’. I’ve discovered that I can readily identify these by filtering for ‘Unknown’ transaction type! The rest of the discrepancies have been ‘Draft Orders’. Doesn’t make sense that ‘Draft Orders’ is listed as a Sales Channel, but Shopify doesn’t list ‘Draft Orders’ in the All Channels drop-down menu.
