This would be so useful, if it’s so quick and easy to create the assocaition via an import, it needs to be as quick to undo those steps.
We’ve just imported 150 donations against a single company via an import and now we have to manually remove that association one by one. Insane! Please develop this feature, anything that can be done in an import, needs to be undone just as easily.
In fact, being able to delete imports would have also helped our particular situation!
