soapUI: multipart form-data. i don't know how to post form-data

i used 'postman' to test my api, the media type of body is form-data.

the HTTP code：

POST /xxxxxxxx/xxx HTTP/1.1
Host:  xxx.xxxxxx.com
X-ML-AppId: xxxxxxxxxx
X-ML-Request-Sign: xxxxxxxxxxxxx
Cache-Control: no-cache
Postman-Token: xxxxxxxxxxxxxxxxxxxx
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="userId"

123123123123
----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="content"

textContent
----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="latitude"

10
----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="longitude"

50
----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename=""
Content-Type: 


----WebKitFormBoundary7MA4YWxkTrZu0gW

so, i want to run this test case in the testSuite of soapUI, but when i chose the media type to multipart/form-data, i have no idea how to input the key and value of form-data.

like this:

i just want post form-data like postman.
