How to create a rule based on "Inbound"?

[turtle-ca-chan]

Hi! Can you please advise if it is possible to create a rule based on "Inbound"? I have tried using 'INBOUND,Socks5' but this gives the error "parse rule error:[unsupported rule type Inbound]"
I need to set such rule to enable full traffic proxying for any application which uses OpenClash's proxy server on 192.168.2.1:7891 (this is [My router IP]:[Socks5 Port])
I don't need to enable proxies globally and I still want to use customized proxy rules for most sites. But I do need to be able to proxy all application traffic if I setup OpenClash's proxy server 192.168.2.1:7891 for it.
It seems to me that such implementation should be possible, because OpenClash distinguishes between Inbound types:
