Full backup from subdirectories backups

Suppose that in a system, there are backups of some subdirectories, name them D:\data\incoming and D:\data\outgoing or /data/incoming and /data/outgoing, running regularly since some time ago, with full backups happening in different weekdays.

After that situation is well established, it comes the necessity of having backup of D:\data or /data as a whole, but a full backup is incovenient because the amount of data would be enormous.

Is it possible in Networker to make the system create the first full backup taking advantage of the existing subdirectory backups?
