Good morning everybody, i am having an issue when trying to apply customer payments using SOAP

<soap:Body>
        <ns0:add>
            <ns0:record ns2:type="ns1:CustomerPayment">
				<ns1:customer externalId="GP-UTZ_TE1000001330"></ns1:customer>
				<ns1:payment>1000</ns1:payment>
                <ns1:department internalId="35"></ns1:department>
                <ns1:location internalId="308"></ns1:location>
                <ns1:autoApply>false</ns1:autoApply>  	
    			<ns1:applyList >
                	 <ns1:apply line="1"  apply="false"/>
                	 <ns1:apply line="2"  apply="true"/>
                	 <ns1:apply line="3"  apply="false"/>
                	 <ns1:apply line="4"  apply="false"/>
        		</ns1:applyList>                  
            </ns0:record>
        </ns0:add>
    </soap:Body>

This throws an error

<platformCore:code>USER_ERROR</platformCore:code>
                        <platformCore:message>Adding new line to sublist apply is not allowed.</platformCore:message>

However, the same code, without the applyList tag works fine,

<soap:Body>
        <ns0:add>
            <ns0:record ns2:type="ns1:CustomerPayment">
				<ns1:customer externalId="GP-UTZ_TE1000001330"></ns1:customer>
				<ns1:payment>1000</ns1:payment>
                <ns1:department internalId="35"></ns1:department>
                <ns1:location internalId="308"></ns1:location>
                <ns1:autoApply>true</ns1:autoApply>  	
            </ns0:record>
        </ns0:add>
    </soap:Body>

 How can i manually specify which invoice or line number i want to apply? I am using 2020_1 web services
