Change port & password in all servers at once?



I have one problem with shadowsocks app (Android): the shadowsocks function of my VPN provider sometimes gets disabled on their www, and I need to enable it again. After that the remote port and password are changed.
Currently I have maybe 200 different servers (profiles) in my Shadowsocks app (Android).

Is there a way to change the port and password to the new one in all those servers at once? Maybe some special plugin? Or a different shadowsocks client that can do that?
It is terrible to change those two settings in 200 servers one by oneā€¦


Use import/export JSON to do batch editing.


I know about the json function, but how to use it for batch editing? Could you please elaborate?
