Why does keil erase softdevice hex and the app hex when doing a clean build?

[Craig]

I am trying to figure out how/if I can program the softdevice hex from keil? I know I can just use nRF studio however its annoying sometimes....I also noticed I cannot rebuild the softdevice hex and when you do a clean all it literally erases all hex from project including the softdevice, how can I prevent this and/or why is this happening?

Thanks that's a really great article however it only answers about half the question....I need to know why and/or how to stop the Keil IDE from erasing the softdevice HEX file from the directory when I do a clean build...it erases the HEX from the project which is fine but I dont want it to erase the softdevice as its annoying to copy back all the time after hitting that function.
