Tailscale Funnels - Multiple Services per Machine?

So, Tailscale Funnels are amazing. Really appreciate the dev effort on this, as it’s so much easier to use than reverse proxies. Huge kudos.

Question for you: How do we allocate more than one service per machine? The convention for setting proxies appears to only work with the root domain, unless I’ve misunderstood the docs.

To clarify, the convention for proxies reads as below, where ‘/’ refers to the root of machine.tailnet.ts.net.

tailscale serve {/} proxy {port_number}

Is there any way to have it proxy to subfolders, like so?:

tailscale serve {/subfolder} proxy {port_number}

Or is there another way to funnel multiple services for each machine?

Thanks again, and in advance!
