Tuning in general by DNS names

[izidood]

Hi SO Team.
Do you have plans for implementing the possibility to tune by DNS names rather than just ip's?.
i know theres Suricata variables, but sometimes it just doens't get the job done.

i could filter out an alarm from a user which is working with something that might look sus, but i know its a falsepositive.
and when that ip gets released and another gets the ip eventually, its all over again with the tuning, as the user gets a new ip?

you support reverse-lookup which is nice, but would be cool if this was a feature.
