Can Siri recognize multiple addresses in Contacts?

I'd not noticed this before, but I tried it to see.

While Contacts does support multiple addresses, Siri seems to only recognize 'home' and 'work' as automatic navigation destinations... e.g. 'Navigate to John Doe Home', or 'Navigate to John Doe Work'.

Other address labels including the standard 'School' and 'Other' options, as well as any custom options are not triggered via Siri (at least in my testing).

That leaves you with a couple of options. None of which are ideal.

If you 'Navigate to John Doe' and John has multiple addresses, Siri will offer a list of addresses you can choose from. You need to physically interact with the phone, though, since you can't select from this list via voice.

Second, even though this is a business, you can set one of the addresses as 'home' and trigger this via the automatic navigation. Again, not ideal, but if it's only you using this it may be doable.

Third is to report it to Apple via Product Feedback - Apple asking them to support Siri Navigation to more than 'home' and 'work' keywords, probably via the Maps feedback link. Not a short-term solution, though.
