Add TTL value to local DNS records


Would it be possible to add a "TTL" box next to the local DNS records?
All my local DNS records are entered here, but I have some local devices who keep spamming the network so for these I set TTL to a higher value, because I can't enter TTL I have to create a seperate .conf file for those records, it would be nicer to have this in 1 list, also because it will be synced then with gravitysync to my 2nd Pi-Hole.
