Yes, CB Auto Actions can modify reference variables if you know what variables are references and specify them as such under the Parameters tab. You'll need PHP to do this so it has to be done either in a Code action or in Output (typically you'd use Code action). Example as follows.
Triggers: onBeforeUserUpdate
Reference Variables: Variable 1
Code:
Code:
$variables['var1']->set( 'cb_phone', 'home' );
The below could may also work.
Code:
$user->set( 'cb_phone', 'home' );
Not entirely sure why you'd need this though. Recommend having multiple phone fields for different phone types or having a select field for them to select the type of phone number.
