Getting individual accounts for each investment in American Funds/Capital Group

American Funds (as best I recall) downloads as a one-fund to one-account  process.  So if your broker is buying a new and different fund each time, you'll get a new account each time.  

Your other options are a) manual entries into a single account or b) after getting the downloads, move the transactions to a composite (manual) account.  [I have never tried option b so I can't comment on other issues that might arise.  There could be several.]
