Is there a way to set-up Geph to filter specified apps on PC?

Title. I need it mostly in two modes - either full proxy for browsing or only make Discord connect through whenever I am playing games. Is there a way to manually set up Geph to only filter traffic of particular connections or websites?

And "not filter PRC content" isn't what I mean because there are foreign connections that don't get blocked by GFW

一般不要开启全局VPN或系统代理,需要爬墙的应用尽量在其内部设置代理,如浏览器采用代理扩展(内外网自动+手动处理之必备神器!)控制,可同时正常运行N个代理端口不同的代理软件。。。

是指国内用户访问国内网站,不经过迷雾通而直连。
