ASUS GT-AC5300 adding DHCP Options (stock firmware)

[QuestorZ]

I know that Merlin does not current support a firmware for the "GT"-AC5300. I got one on a deal and was curious if there was some way I could set DHCP options on the stock firmware via SSH/CLI. I have created a scripts directory in /jffs and put my options file in but obviously it doesn't work since it's not kicking it off/symlinking/etc like Merlins firmware. Really the only thing I need is to be able to set DHCP options and I would be happy with this unit the way it is. This thing is a beast and it would be serious sad face if I had to run an external DHCP server so I could set the VoIP options I need. Thanks for any help!

Current options I need to set:
dnsmasq.conf.add

dhcp-boot=pxelinux.0
dhcp-boot=pxelinux,192.168.2.12
dhcp-option=2,-18000
dhcp-option=option:ntp-server,192.168.2.12

Stock firmware does not support custom config/scripts. That's is a feature I added in my firmware.
