Is it possible to annotate PDFs within Zoho WorkDrive or any other Zoho application? Different than just adding a comment. Can we do basic things like adding an arrow, or drawing a box around something? We need to point out specific things on graphic images. Like circling part of the image and asking for changes. Typical PDF editing for corrections when working with clients. We'd love to find a Zoho solution, but we haven't (yet).

Thanks!
