Tell us about your request
It would be good for example for maven projects that use docker multistage build to have to option to add all files of a type to the docker build keeping the folder structure so in case of a maven multi module project all the pom.xml files so you don't have to add them one by one like:

copy pom.xml pom.xml
copy module1/pom.xml module1/pom.xml

This way the docker build cache can be used more efficient

Which service(s) is this request for?
