ssh-agent - use specific key for specific hosts

Using 1Password SSH keys has worked fine until I crossed a threshold in the number of keys whereby some hosts don't like how many keys they are offered. I found this old thread that describes how to customize the agent.toml file to indicate which keys are presented, but that doesn't really help when I have a number of vault keys I need to use. I could resequence them using agent.toml, but I'll just have this same problem with one host or another.

I basically need to somehow map prevent ssh-agent from scouring the entire list. The thread above indicated that there would be future work on this - it might be that I'm just asking for an update.

      Even using the Bookmarks feature presents the same failure (basically too many keys being presented to the remote host). The target devices are serial console multiplexers, and may not have the typical OpenSSH or LibreSSH stack. It's really important to not present too many keys to the target.

      As an aside, using this feature with other hosts works fine on my Mac, even calling an external terminal program (iTerm2), but it would be nice if the Windows version were better integrated with other terminal programs such as SecureCRT. I'm not sure how much could be done there given how miserable Windows is.
