Dot notation for MB Geolocation "type"

I may be missing something obvious, but I've tested and searched on here to no avail.

Here's what I'm trying to do:
- Using MB Builder + MB Geolocation, set the "Types" option to return 2 types. Like in the example on the MB Geolocation docs, I would like to set it to "(cities)" and ""establishment"

'geo' => array(
    'api_key' => 'YOUR API KEY',
    'types' => array( '(cities)', 'establishment' )
),

How can I do that in the Settings tab of MB Builder?

I tried adding a custom attribute of geo.types => [{"establishment","(cities)"}]

But on the front end I get the following error:

InvalidValueError: setTypes: not an Array
_.Wc @ js?libraries=places&key=AIzaSyDgNeQLcJwxuVJC8yC_F1HYfXONXoTVaxc&ver=5.2.2:60

Can this be done with MB Builder + Geolocation?

Thanks for your help.
