Parental control - https sites

hi,

I`m using Trend Micro Parental control function but lately it has become less useful since more and more adult sites are going to https, and router cannot block this site :/
Does anyone know if the asus is going to do something about it or will eventually stop working completly ?
For comparison, I recently tested synology RT2600ac and has no problem with blocking https sites.

br,
Michał
