Hooking OW up to existing Keychain entries?

I’ve got a number of Keychain entries, either saved in Safari or older OW builds that the current builds of OW are not recognizing.

Is there a way to have it read the existing Keychain entries or, like Safari, give an option to search through them after unlocking?

Note that this really isn’t a high-priority item, just wanted to get some info if OW should be showing options for the fields, or if something else is awry.

I’m running 10.14.6 with all the updates installed.

Thanks.

Cheers,
Jon
