Routing Strategy                                       Route to Property name
p10001                                                 ${project_id:matches('p10001')}
p11012                                                 ${project_id:matches('p11012')}

Here is the answer I provided on the Github issue against future need:

from nipyapi import canvas, nifi
# Test adding a custom Property
test_prop = {conftest.test_basename: 'test'}
_ = r1.component.config.properties.update(test_prop)
r2 = canvas.update_processor(
    r1,
    nifi.ProcessorConfigDTO(properties=r1.component.config.properties)
)
assert conftest.test_basename in r2.component.config.properties.keys()
# Test removing a property
r3 = canvas.update_processor(
    r2,
    nifi.ProcessorConfigDTO(properties={conftest.test_basename: None})
)
assert conftest.test_basename not in r3.component.config.properties.keys()
