I understand how to read from an external file, but i am trying to read from a list of items/blocks, but I can't quite get how to do that. And what I mean is like:

```
on pickup:
if item is {antyhing from common_items.txt}:
set the 1st line of the item's lore to "&f&lCOMMON"
```

Because I don't want to add a long list into my script, and I want it to be like external so it's easier. Thank you.
