During step 13 of this guide https://www.hovatek.com/forum/thread-21970.html WWR extracts the preloader from the dump from the boot partition.

How does it extract the exact filename of the preloader too e.g. preloader_gionee6580_we_m.bin?

This info is contained in the raw preloader dump. You're dumping preloader, pgpt and full dump (depending on which version you're using)

After taking a full dump of the device, WWR is unable to build the firmware for some reason and instead i need cut the rom instead on the Scatter file tab. But because cutting the rom doesnt add the file extensions to the sliced partitions, can i simply just add .img/.bin to the end of the sliced partitions e.g. turn logo into logo.bin and system into system.img?

use latest v2.51 or if using an older version then you should include your chipset type in template.ini along with the scatter file version it should use

yes, you can add file extensions
you will also need to modify the filenames in the created scatter file too
