Zoho Flow - Creator to Excel. Add row to excel sheet using Creator Subform fields

I've created a flow which adds a new row to an excel sheet on submission of a Creator Form. It pulls through all the form fields i require EXCEPT for the Subform fields. Is this a known limitation of Flow or is it something that can be done? Guidance required please. Thanks.
