Migrate support

Trying to work out how to map data from a migration to a View Reference field. I have tried the following within the Migrate definition:

$this->addFieldMapping('field_sci_view_to_use:arguments', 'pdbid')
     ->description(t('The default value to use as contextual filter for the view'));

where field_sci_view_to_use is the View Reference field.

I have examined the module code and found that arguments has two further subfields of php_arguments and dsv_arguments. Do I need to directly map to either of these fields? What is the correct syntax for this? Is there even Migrate support within this module?

Any help welcome.
