We already have this in our backlog, but I think it will take some time to get there. The whole idea is to make it easier to work with big number of campaigns and promotions, exactly how and when is undecided, however.
Thanks for the quick reply :-)
When having a large amount of discounts it would make them easier to manage if it was possible to implement custom sort and filtering for the discount priorities and exclusions view.
This also applies to the campaign view that already supports filtering but lacks custom sorting.
The view in question:
Commerce -> marketing -> discount priorities and exclusions.
