Official lists for short episode dramas?

Is there an official list  for short duration episode dramas, per channel or per producer?

I like watching short episodes when my days are busy. They also contain less product placement scenes. 

I have found some user-made lists, but I'd prefer an official one. User-made lists are great if you like the same type of plots, but they are not of much use if you search for a broader range of stories or for more variaty in the cast.

Thank you!

I had a look and it also lists dramas with short count of episodes  (eg a total of 16 episodes of 40') not just short-length episodes, but it looks like what I need.

I'm sure I'll find something, it has pages and pages of content!   :)

glad to help you
