Currently, users can access a link to a task by clicking the "chain" looking icon; a convenient feature. Unfortunately, there is no way to access a link to an attachment that is uploaded to Wrike.
When providing updates to a task, where a number of attachments are uploaded to Wrike as part of the update, it would be convenient to be able to just paste a link as part of a sentence within a paragraph of an update.
I recommend an option "copy link" when a user right-clicks on an attachment that has been uploaded to Wrike. The link can then be pasted as a text or a hyperlink as is currently done with "task link".
