Foreman requiring each host to have individual file for PXE boot

I was using Spacewalk with the default pxelinix file which build all hosts. In Foreman I’m required to create a configuration per host using the MAC address.

Expected outcome:
I’d like to be able to just use the pxelinux default file for all hosts. I understand that each host gets a token when I select build. The token allows me to deploy my host. In Spacewalk I used to just boot my host to install it. Is it possible to configure the default file to allow me deploy hosts?

Anybody know if it’s possible to just use the pxelinux.cfg/default file with a generic line covering kickstart builds rather than creating one per MAC which happens when I select “build” in the foreman interface?
