Exclude a directory from thrashbin?

Hello,

can I exclude a directory from trashbin? So that deleted files are directly deleted and doesn’t
into the trash? I have a backup solution with obnam and this stores the files in chunks.
And therefore there are a lot of files in the directory and send the to thrash makes no sence.

I’m not sure, but maybe there’s a way to configure workflow and file access control to make that happen.
