It would be nice, to have the receipt of my payment copied to the expense I add in a slice group using the split function in a payment.
Example: I scan and match my receipt and afterwards I split the payment using the split function and the slice group. In the slice group it then just says where the payment went to (for example a grocery store), but you can't see the receipt in the slice group. I also can't add the receipt or even a comment when using the split function afterwards.
