Add app to Firewall tab

Is there is any ability to add some app to Firewall tab?
Because it’s not good if I only able to block app after its first appearing.

I believe the intent of the firewall tab is to keep relatively trusted Windows apps from communicating out. By decreasing the amount of applications communicating to the outside world you draw less attention to your PC.

If you want to block an app from communicating with your PC from outside your router, then you should set it up at your router’s firewall and/or at your PC’s Windows firewall.

We’re working on something that does this with a future version of GlassWire. Thanks for your feedback!
