Wildcard re-directs to externally hosted subdomain

I have not been able to find any recent posts on this subject and older posts seem to insinuate that this isn’t possible.

I have a client that is trying to move its main website over to Webflow, but keep the blog on its existing platform as it would be a huge pain to transfer the blog. But in order to not kill SEO on the blog posts, we would need to have all of those links transfer to the new subdomain.

So for instance, all 100 or so blog URL strings would need this re-direct:
company.com/blog/… –> blog.company/post/…

Is this possible somehow?
