1Password SSH Agent how to set specific ssh key

I have a few different ssh keys that are used for git and would like to have it set so that if going through one github organization i force one key if going to a personal account it uses a different key.

Is there any way as part of the IdentityAgent to specify the appropriate key or is the option just to keep cycling through the prompts for ssh keys?

    I've been able to achieve this with git's conditional includes. Here's what a config may look like:

    # ~/.config/git/config

    [include]
        path = base-config.inc
    [includeIf "hasconfig:remote.*.url:*:jc00ke/**"]
        path = personal-config.inc
    [includeIf "hasconfig:remote.*.url:*:WORK/**"]
        path = work-config.inc

    # ~/.config/git/personal-config.inc
    [user]
        name = Jesse Cooke
        email = jesse@example.com
        signingkey = ~/.ssh/personal.pubkey

    # ~/.config/git/work-config.inc
    [user]
        name = Jesse Cooke
        email = jesse@work.example.com
        signingkey = ~/.ssh/work.pubkey

    Here's my real dotfiles; this has worked for me for a while now.

    You can specify which key to use for which host in ~/.ssh/config using IdentityFile option, where the identity file is the public key to use and the private key is stored in 1Password. You may also need to specify IdentitiesOnly yes.

    Example for user99@example.com:


    Host example.com
    User user99
    IdentityFile ~/.ssh/identity.pub
    IdentitiesOnly yes
