is it possible to activate 'Edit in Place' for xlsm-files (Excel Macro-Enabled Workbook file)?
For xls(x)-files there is the link 'Edit This File', but not for files of type 'xlsm' allthough they could be dealt the same way with Excel.

I know I can edit this files using the 'Add-in for MS Office' and via the 'Vibe Desktop', but it would be nice to deal them like other Excel-files.
