Hello again @ttim03,
Custom icons for items are not yet supported in 1Password 6 for Windows, but it's something we'll be adding in a future update.
You can stay updated with the latest release notes here. Thank you for letting us know you are waiting for those!
If there is anything else we can help you with, feel free to reach out to us anytime.
