Allow magic links directly to website, skipping [...].supabase.co/auth (for PKCE)

When I do PKCE, I send users to /login/auth where I run exchangeCodeForSession(), then to a page the user should be sent to.

That means I get an email link containing a redirect containing a redirect, like this:

https://example.supabase.com/auth/v1/verify/?token=pkce_5183cf9731f6a8fb22443be56304f7b36d9a10b90f5fdc2e5c218891&type=magiclink&redirect_to=https://mywebsite.com/login/auth?redirect_to=/account

It would be great if the email link could be just https://mywebsite.com/login/auth?redirect_to=/account instead. I'm already calling exchangeCodeForSession(), so I assume this would even reduce latency.
