Multiple ssh keys supported?

I have multiple ssh keys. There's a slew of use cases for this, but i use different keys for different clients, environments & differentiate my home/work identities.

I just enabled the ssh agent, updated my ssh config with the following:

❯ ls -al ~/.config/1password/
lrwxr-xr-x@ - user 24 Mar 09:23 agent.sock -> '/Users/shawn/Library/Group Containers/****.com.1password/t'/agent.sock
❯ cat ~/.ssh/config
...
Host *
IdentityAgent "~/.config/1password/agent.sock"
...

I confirmed I'm able to ssh to different endpoints without storing my private keys on disk. awesome!

However, i'm having a couple hiccups I'm hoping someone can help with (I did read the docs, and search forum - so sorry in advance if I missed this)

First, I have different Github accounts, and have managed them to date with something like this in my ssh config file:

Host home.github.com
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_ed25519_home
    IdentitiesOnly yes

Host github.com
    HostName github.com
    User git
    IdentityFile ~/.ssh/id_ed25519_work
    IdentitiesOnly yes

Is there a away to name identities, or fingerprints, with the 1password ssh agent?

Also, what if i only want 1 or 2 of my keys loaded? It looks like, by default, its loading ALL my keys i have. No biggie if I could `ssh-add -D`, but that is not letting me delete any. Is there a way to tag/flag keys i dont want loaded by default?

I looked at the advanced examples (https://developer.1password.com/docs/ssh/agent/advanced/#mac--linux), but all the examples expect the private keys to be stored on disk. Honestly, if i need to store on disk, i'm wondering if the 1password ssh agent is for more basic usage?

Please help :)
