Activity notifications to indicate when a file is open by another user

Hi Owncloud community!

Is it possible to configure activity notifications that tell us when a file is open by another user?

For example, we have a shared folder in Owncloud between several users and when we edit some document at the same time, sometimes there are conflicts in the file.

We would like to know if Owncloud itself has the option to generate a desktop notification to alert us when you open a document that has already been opened by another user.

Hello

Nobody knows if it is possible?

Thanks
