Can I retrospectively add tracked events to newly set up goals?

I haven’t found a very clear and recent statement on that question, but rather vague hints that historical “data” can be integrated “for example” into a new funnel or custom report by invalidating existing reports.

Having invalidated reports repeatedly and waited for populating funnels after having added new goals, I tend to assume that there is no way to apply additional goals to existing data. Can somebody confirm or is there still a way to make an historically tracked event a conversion based on a newly set up goal?
