Query currency rates with shorter syntax in Google Sheets

I'm aware of the GOOGLEFINANCE function provided by default in Google Sheets:

INDEX(GOOGLEFINANCE("CURRENCY:GBPUSD", "close", A2), 2, 2)

However, as you can clearly see, it takes ages to write. Plus, it makes functions less comprehensible. Is there a middleware that has a lighter syntax? Maybe something that doesn't need the INDEX function?
