Hi, 

You're not alone with this request! Unfortunately I wasn't able to join the 
2-day Galaxy Hackathon, but I heard from a colleague who just came back that 
this was one of the topics they worked on. At the end of the hackathon they had 
a working prototype:

https://wiki.nbic.nl/index.php/NBIC_Galaxy_Hackathon_project#Loop_over_files_in_a_directory

Since they had only 2 days, it will need some polish, but I heard this hack 
already made it into the development branch of Galaxy, so we may see something 
like this in the near future :)

Cheers,

Pi
