eBay aggregate non-sales charges

Hi, I’m using the automated eBay feed. When importing itemised sales, “advertising fee” and “miscellaneous fee” (e.g. insertion fee) are easy to categorise separately.

However, when importing aggregate totals they are joined as “aggregate non-sale-charges”, meaning they can’t be categorised separately.

Would it be possible to separate the fees when importing aggregate totals? I’d like to use aggregate totals but still see how much I’m spending on advertising.
