Content-Disposition Name

I was wondering if there was any way to remove the quoatation from name of the content-disposition when doing a multipart file upload. the api i am connecting to only accesss the name without quotations. 

Expeted:

--e1fbdde9-d4d1-4038-b7a6-47c535b390fd

Content-Type: text/plain; charset=utf-8

Content-Disposition: form-data; name=fileType

SoapUI:

------=_Part_0_41673494.1447705176576
Content-Type: text/plain; charset=UTF-8
Content-Disposition: form-data; name="fileType"
