Multiple SWAs under paths to the same Front Door host

Hi,

Just trying to work out if it's possible to use Front Door to stich together multiple SWAs under different paths under the same endpoint hostname (e.g. site1 -> fdhost root, site2 -> fdhost/admin, etc).

It's trying to secure them that seems to be the sticking point (as the AAD auth redirects expect to go to the root). Trying to get use the same app reg to secure each SWA (with redirect to the FD host URL) seems to be a non-starter (401s or redirect loops abound when I tried that).

Just wanted to ask the brains trust if this is a fools errand, or if I'm just missing something obvious.

Thanks for your time 🙏
