Publish custom files with Visual Studio22 even in singlefile mode

Question

I know that i can include additional files in the publish step using this

<ResolvedFileToPublish Include="..\ReadMe2.md"> <RelativePath>wwwroot\ReadMe2.md</RelativePath> </ResolvedFileToPublish>

in the publish profile xml

The problem is, that if I select file publish options --> "single file" there is no additional file in the publish folder. Is there a way to still include additional custom files even when using single file publish options? Thanks for any hints!
