SOAP Query - Passing parameters from another query to second query's M-Code

Hi, 

I have a SOAP service (Quinyx) to which I connect to via Power Query. The M-code that works in simple situations is presented below. The issue is, that the employeeId field is mandatory in the SOAP service to which I connect to. Basically the service demands and returns only 1 employee at a time. We have hundreds of employees. I can get a full list of employeeId's with another query to Power Query, but what i need to do is to pass all employeeId's to this request automatically. 

Is this possible in any way in M-code, Python or R? What is the method that should be applied to solve this issue? 

let

SourceURL = "https://rc.quinyx.com/FlexForceWebServices.php?wsdl",

options = [ #"Content-Type"="text/xml;charset=UTF-8",
            #"Connection"="Keep-Alive"
          ],

WebContent = Web.Contents(SourceURL, 
    [Content=Text.ToBinary("

            <!--Optional:

         </getTimePunchesRequest>
      </uri:wsdlGetTimePunches>
   </soapenv:Body>
</soapenv:Envelope>

"),

Headers=options]) ,
XmlContent = Xml.Tables(WebContent),
    Table = XmlContent{0}[Table]
in
    Table

Thank you!
