Automatic folder cleanup

I’d like to ask if there is a way to automatically delete old e-mails in certain folders, something like ‘folder cleanup’.
For example - I have a folder with all kinds of promo offers from various sites and I’d like to maintain there only messages not older than 14 days. 
Thank you!

Hello Zdeněk,

We’re sorry but this is unfortunately not possible at the moment.

With apologies,

Hi Maurice,

Thanks for your reply! Is it considered as a feature for future versions or can I submit it somewhere as an idea?

Hello Zdeněk,

I’m not aware of this being considered a future feature. I changed this thread to Idea so it is now possible to vote for it. Thank you for the suggestion.
