Overwriting a payload file

[yuvnith]

Our WiX3 installers make reference to a payload group that contains the BootstrapperCore.config file.

<PayloadGroup Id="CoreLib">
  <Payload Name="BootstrapperCore.config" SourceFile="Payloads\a.config" />
</PayloadGroup>

In a particular situation, we would like to overwrite BootstrapperCore.config in a single installer. WiX v3 allows us to accomplish this as seen below.

 <BootstrapperApplicationRef  Id="ManagedBootstrapperApplicationHost">
   <PayloadGroupRef Id="CoreLib"/>
   <Payload Name="BootstrapperCore.config" SourceFile="Resources\Payloads\customA.config"/>
 </BootstrapperApplicationRef>

The existing configuration is replaced during runtime by the customA.config. However with WiX v4, we are unable to accomplish the same result, and it acts in accordance with the documentation.
"Each payload in the bundle has a relative file path that is used when the payload gets cached or extracted. In v4, collisions are detected."

Error in WiX 4 - The Payload 'pay8C8TM23OiETbMEoCJIsVFIgOkUc' has a duplicate Name 'WixToolset.Mba.Host.config' in the BA container. When extracting the container at runtime, the file will get overwritten.

Is it possible to overwrite the payload in WiX v4 using a workaround? Would someone kindly provide a suggestion?
