I am taking intra-year to mean that you don’t want to span multiple years. Either way the answer would be the same, if I understand you correctly. All you do is create your goals, categorize transactions as they come in and it should do the rest unless you don’t keep to your goals, then you need to rebalance.
For best practices, I would watch the 4 videos I have linked here. If you don’t have the time, at least the first one.
