Batch export does not honor the scene name. It instead renames to Enscape's chosen file naming method.
Named scenes are important to keep the same for multiple reasons - a few of which listed below:
1) Files are often linked/synced across apps. New file names breaks these links and makes updating presentations tedious and messy. We should be able to overwrite the fileson export as well.
2) Gives users some context for what it is.
