price from postings

Is it possible to have `bean-price` fetch **undeclared** commodity prices from postings, for example, having this posting below:

```
2021-10-28 * "APPLE.COM/AU              SYDNEY  " ^airpods-3
  Liabilities:CC  -279 AUD
  Assets:AAP3    1 APPLE_AIR_PODS3 @ 279.00 AUD
```

and with `bean-price` to "fetch" from the `.bean` file and generate the price entry for `APPLE_AIR_PODS3`?
