Something I would love to see is to have a fallback property for the personalisation tokens. I know that you can set default values for the tokens but it would be great if there was an option to insert a different property's value if the personalisation token is empty.
Use case
We are a holiday company and we send an email 1 year after a customer's last holiday saying "It's been a year since you went to Crete". We always have the country they went to (in this case, Greece), but we don't always have the specific region (such as Crete), so it would really help if there was the option to apply a filter on the personalisation token that says "If Last Booking Region is not known or is empty, use Last Booking Country instead"
