The YAML definition of a form only allows the specification of a  
single column name.

However, you could add an accessor into one of your Result classes to  
get the text you like to expect as a label for the Select element. To  
avoid lots of trivial selects you should add a 'prefetch' attribute  
into the model config like the example below if the columns involved  
sit in different tables.

<snip>
# in my Result::Info I concatenate the name of a foreign table  
'infokind' with name
sub description {
     $_[0]->infokind->name . ' / ' . $_[0]->name;
}

# in my form.yml I can simply use it...
- type: Select
   ...
   model_config:
     resultset: Info
     label_column: description
     attributes:
       prefetch: infokind
...
<snap>
