Direct link to files and possibility to edit them in preview mode

There is a possibility in Wrike that allows to put a link to a Word format file, which allows to attach a file in a task and link to that file (not to task) from another task. Yet, it is not allowed to edit file in preview mode when opening from a link. It would be very appreciated to have a feature which will allow not only open file by a link but also edit that file. Merover, we will offer to have this feature not only for Word format but also for Excel as well.
