Allow adding description of expense when forwarding via email
I'd like to be able to add a description of an expense when forwarding via email. That's generally the time I know what it was for, but sometimes by the time it comes to go through the expenses and add other details I've forgotten. This is especially true with Uber receipts, but it would apply equally to anything else. Would be a genuinely useful feature – if it's not already somehow built in and I haven't been able to figure it out!
