Multiple apps under same domain

I started migration of our apps to Netlify but noticed that I cannot use same domain for multiple applications.
We need to run 4 applications under same domain based on params in the path.
e.g. domain.com/e/, domain.com/blog/, domain.com/r/
Whats the easiest way to set this up?
One idea I have is to create monorepo, but will this work?
Any other ideas or integrations with other products which will make it easy?

Hey @jokuja,

The easiest solution would be to have all of these in one repo, for sure!
