Hi team, 
I have a quick question about the partial parallel pipeline.
I'm thinking of a pipeline: node_1 -> node_2 -> (parallel) node_3_1, node_3_2
is this possible to define in pipeline.py?

so I would actually do this via your run commands

Kedro only lets you provide a single runner for a single run

so the way to do it is with your CLI commands

`kedro run --pipeline=a & kedro run --pipeline=b --runner=ParallelRunner && kedro run --pipeline=c`

`&` will run both commands simultaneously
`&&` will run the second command once the first has exited

it's not a perfect solution, but if you really want partial parallelisation thats (I think) the best way to do it
