Possibility to output to multiple attributes during attribute calculation

[LeonardPuettmann]

Is your feature request related to a problem? Please describe.
I was using a bricks module to get results from a search engine in refinery, which returns info such as a text, date, URL etc. It would be useful if it would be possible to store each of these in a separate attribute instead of just one.

Describe the solution you'd like
Don't have one at the moment.

Describe alternatives you've considered
The result I get is a large JSON file, which I save to a string representation to be able to load and use again at a later point.
