Sub categories or sub groups

[tonnyavery]

I want to have a bucket for trips, but within that bucket I would also want to have sub-categories, eg. Food, Rent, Transport and so on. I don't want to budget them as separate buckets, but would be great for statistic to know how much did I spent on vacation rent

Funny, just back from a trip where I had the same thought !
