If you have to delete a lot of rules, it is painstaking and time consuming. My client has set up Rules for deposits prior to implementation of invoicing. Now, so that the rules don't override the matching to the invoice, we have to delete - there must be at least 50. Click to get to the edit screen, then cancel, then find the rule you want to delete because the list has changed and the cursor is not where you left it, then click delete then click yes to delete. What a complete waste of time. Surely there should be some way that you can 'group/click using control or something that would allow you to delete more than one.
