PreUp/PostDown keys not supported in WireGuard Config

Hi!

I am trying to use PreUp/PostDown directives as mentioned here. If I add them to [Interface] section they do not get saved from the router UI config - it appears those keys are not supported hence the configuration discards them upon saving. Is there any way I can add them at the start/close of WG VPN connection?

wg-quick script is not installed on the router, you can run the commands manually.
