How to link to a first or last document in a container?

Hi!

I need to link to one document in a container, it could be the first created or the last one...
(because people will be adding new contents, and I do not know the name/alias of those new created documents...)

Is there any way to achieve that?

Look for the snippet FirstChildRedirect

Thanks for the tip rtrash!
I will look at that...

and I found [!Wayfinder? &startId=`57` &level=`1` &limit=`1`!]

that maybe do what I need (it is not right defined yet)
