Have to be able to modify the blind scan plugin located at /usr/lib/enigma2/python/Plugins/SystemPlugins/Blindscan
No i'm not smart to do it, one mistake and you get crash.
As for TNAP you can replace to blind scan folder form the Satdreamgr-6 image dated around the same time as TNAP January 2019 and reboot the box and then you will have the original Satdreamgr Blind scan. Backup your TNAP image first.
