Set up local proxy and tunnel it through a profile

[EasternTime]

I don't use my profile as VPN, instead I use it in Tun mode and let only selected processes through using processName. Recently I noticed that some of my programs work poorly with processName, but fine through http/socks5 proxy. Thus, my goal is to run http proxy server locally, and run traffic from it throuh my profile.

In Basic Settings -> Common -> Custom Inbound I set up a proxy server:

{
    "inbounds": [
        {
            "listen": "127.0.0.1",
            "listen_port": 1081,
            "tag": "httpproxy-in",
            "type": "http"
        },
        {
            "listen": "127.0.0.1",
            "listen_port": 1082,
            "tag": "socks5-in",
            "type": "socks"
        }
    ]
}

I can see that the proxy server is actually up and running correctly. However, if I try to use these inbounds everything that goes through these proxy are going to direct, no matter which routing profile I choose.

It may be corrected by adding this custom rule to Routing Profile -> Edit -> Advanced tab:

{
    "action": "route",
    "outbound": "proxy",
    "inbound": ["httpproxy-in", "socks5-in"]
}

It's quite inconvinient since I have a lot of routing profiles, some of them are direct by default, some are proxy by default, with various rule sets.

I've got several questions.

1. Can I make it so that these inbound connections respect .srs rules lists and other complex setups?
2. Can I set these proxy outbounds globally, or do I have to set them for each ruleset individually?
3. Why I can add rules in Routing Profile -> Edit -> Advanced tab, but unable to edit them? Each time I have to export the profile, edit it and then re-import.
4. Am I missing an easier way to achieve the same result?
