I have not tried it but would suggest that as the end result of fermented fruits does not taste like the fruit it's self, that the flavour should be added later.
I do make cordials from fruit using vodka and that tastes of the fruit. It is just fruit sugar and vodka mixed together for a few days then remove the fruit. filter out bits and bottle. (the fruit makes great triffles)
My suggestion would be to add a cordial to the cider at the time of bottling to get the flavour right. Or as I do with the strawberry add a measure to sparkling wine as it is served.
