Commenting Function - by: Isaac

Dear all,

GOod day. I would like to just check if it is possible to add in a "comment" function for all the files. At the moment, after the search, we can view the document and some preview of it, however, assuming that we have downloaded and made some changes so, I wanted to add in some comments so that other users who searched and worked on the documents would know the comments I left on it. Will that be possible?

Thanks!
