Set existing libraries file retention / history

I am running seafile on a windows server. i have about 60 libraries used amongst 20 users. I did not have the foresight of setting a default Keep_days before creating the libraries. i now need to set it on the libraries. is there a way to do this?

EDIT: I am a moron. i spelt “keep_days” as “kepp_days”. once i fixed this all libraries using the default retention reflected the change.
