Is there a way to specify pathToContent" when updating external data?"

I set up skuid to pull data from an external data source. I want to also be able to save to this external data source. At this point I’m trying to save the data to the same external data source. it seems however that the “PathToContent” property is not being used when doing an update. Is there a way to specify this property or an alternate property to use as “PathToContent”?

ex.
GET request returns data with

{"Data":[array-of-data]}

PUT request currently uses

{data}

I’d like the PUT request to use:

{"Data":{data}}

Thanks for your help,
