It's not currently possible unless you write a python function to do this.

I've been pondering this week about allowing items to access the variables
from another item but need to think this through more.

My (current) use case:
- working on a map of a train line which consists of three vertical panels
covering different parts of the line
- certain elements (like label buffers) in the map style use a
@background_color variable to data define their color
- each map item in the composition has its own @background_color variable
set so that this color represents a good background color for the visible
content within that panel
- I want to style things like North arrows to reuse the @background_color
variable from the map item they are associated with.
