How to send multiple values ​​to an enum field using soapUi

I am testing a webservice request using SoapUI.

I have a string that acts like a bitwise in my request. The field is an enumeration for SoapUI. In XSD, I have all the enum values.

I need to be able to send 2 or more enum values ​​in fields, but SoapUI only accepts text like "All" or "testvalue2". I would like to send testvalue and testvalue2 for example.

thanks for the help

XSD extract:

<xs:enumeration value="None">
          <xs:annotation>
            <xs:appinfo>
              <EnumerationValue xmlns="http://schemas.microsoft.com/2003/10/Serialization/">0</EnumerationValue>
            </xs:appinfo>
          </xs:annotation>
        </xs:enumeration>
        <xs:enumeration value="Testvalue">
          <xs:annotation>
            <xs:appinfo>
              <EnumerationValue xmlns="http://schemas.microsoft.com/2003/10/Serialization/">1</EnumerationValue>
            </xs:appinfo>
          </xs:annotation>
        </xs:enumeration>
        <xs:enumeration value="Testvalue2">
          <xs:annotation>
            <xs:appinfo>
              <EnumerationValue xmlns="http://schemas.microsoft.com/2003/10/Serialization/">2</EnumerationValue>
            </xs:appinfo>
          </xs:annotation>
        </xs:enumeration>
        <xs:enumeration value="All">
          <xs:annotation>
            <xs:appinfo>
              <EnumerationValue xmlns="http://schemas.microsoft.com/2003/10/Serialization/">255</EnumerationValue>
            </xs:appinfo>
          </xs:annotation>
        </xs:enumeration>
