When I pay something for friends of mine, the whole payment will be noted in Insights and Budgeting, but I didn't spent that all by myself. Therefore, it would be great that if you split costs, Budgeting & Insights will automatically see that a lower amount of money need to be registered.

Also, it would be great if you don't see all the repayments in the list, but that this is shown under the global payment that you did.
