Currently, if a user has a file open in OfficeOnline, that file cannot be opened in Box Edit.
If I want to perform operations that are only possible in the local Excel application (e.g. sheet or macro operations) and a colleague comes home while editing in Online, my work comes to a halt.

Can you please implement a priority lock function that works as follows.
1. click "Priority Lock" on a file that someone is editing online.
2. Only the latest version of the target file is copied to the same folder as a separate file with "(1)". After that, the result of Online editing will be overwritten by the file with "(1)".
3. The file is locked (normal lock) so that only the user who clicked "Priority Lock" can open the file in Box Edit.
4. the results of edits made via Box Edit will be overwritten in the original file.
5. when a user who was editing online resumes or exits online editing, a dialog box will appear informing the user that the file has been saved as a separate file because a user performed the "priority lock" operation.

I think this method could be implemented by adding functionality on the Box side, not by changing the functionality on the OfficeOnline side.
