Add a time lock on the filter settings (and bypass account)

I use a Netgear Router that comes with parental controls via OpenDNS. I must say it works like a charm.

I however would like to request a time-lock feature on the settings, much like a time-lock on a vault.
As the home network administrator i try to make sure that no unwished content enters our home.

While this works fine in most cases i must admit that sometimes i am tempted to browse for content that i will usually want to block. At those moments it feels like i am the alcoholic that also keeps the key to the liquor cabinet. Not a good combination.

I would like to have the option to place a time lock on the settings (and bypass accounts) so that if this situation occurs, there is no way to quickly bypass the filters. In effect creating a 'cool down period'.

Kind regards
