Date in Headline of repeating Project
 

I have several Projects, that repeat every week automatically.
If I doe so the names of theses projects are repeating as well.
I would like to see the date ore the number of the week in the name of each project automatically:

"Test 1.1.13"
"Test 8.1.13"
"Test 15.1.13"

or "Test week 1"
"Test week 2" ...

How could I do this?
