I use a multisite multilanguage Umbraco CMS.
I have something like this: 

```
first.com
second.com
third.com/en
third.com/fr

```

Is there a way to add/manage the `robots.txt` individually for each site...

```
first.com/robots.txt
second.com/robots.txt
third.com/en/robots.txt
third.com/fr/robots.txt

```

in the second instance, the *sitemap* should behave the same way...

(I have the the umbraco v4.7.2)

Using packages like "Cultiv.DynamicRobots" allows only one (even dynamic) robots "per umbraco" installation... and does not permit `third.com/fr/robots.txt`
