Can files be included in the loading of a component but have their changes ignored?

They have a component that contains files they would like loaded into a build workspace.  The build is then performed and may change some of these files.  They want to prevent the changes to these files from being checked in and delivered.  The first thought is to add the files to a .jazzignore file, but it is my understanding that this will also prevent these files from being loaded into a sandbox.  Is there any way to accomplish what they are looking for?

Thank you,

Jamie.
