FeatureRequest: SSH Agent Key access confirm

When using 1password as ssh agent, I miss the lack of possibility to define an ssh key as something like "confirm on each access".
Not only like the current setting options "allow for all apps", "this app" and "this terminal session until closed".

PRO of that feature request:

• better control of usage of a critical key, really on each usage.
  
  
• even with ssh agent forwarding the key would be usable on the remote host but also remain secure due to a second confirm request if it's used again f.e. by another connection created on the remote host.

Would such a feature be possible in near future?

What do you think about that idea?
