Force Ignition to backup \webserver\webapps\main folder

Hello
Is there any workaround to force Ignition when backup a gateway, include
\Ignition\webserver\webapps\main folder in backup zip file?
This folder may contian project specific files like map tiles, PDF, …
Manual copying thos folder along other resources like com.inductiveautomation.perspective for fonts is really hard for each restore in new system.
