We have a multi branch pipeline for a large (20gb) project in SVN. 

Whenever a new branch is created, the entire branch is downloaded into the workspace@scripts directory when all it needs is JenkinsFile. This is doubling up on the amount of disk space that is being used, and increasing the amount of time taken to initially check out the project.

Can this be made to initially try check out just the single file, or a single sub directory first?
