Spreadsheets Editor

I want to do the following:

I double click a document on a view, then open the excel file embedded in the document directly using symphony spreadsheets.

After modification and save, the modified excel file is then replaced the previous one in the document.

The document is never shown to user and just for storing the excel files.

I want something like in 8:30 of

Thanks in advance.

Subject: You’ll want to “edit” the attached document…

Opening the document and modifying it will not replace the existing attachment. To do this, chose “Edit” or “Edit with” from the context menu.
