useMultiMutation() mutation on list views

[posva]

When using a regular useMutation() within a list view, you can mutate different entities but you only get access to the loading state of the last one. It would be useful to allow a version that requires a key to compute the different properties in a Map and then each value becomes a function instead of a computed: data(key), isLoading(key) so we can check the progress

Problems:

• How long should each data be preserved
• Should there be a way to remove the data
• Any difference between errors and successes?
