Edit Read-Only attachment documents

Hi,

When I open an attachment from an email, or download a file from the web, the document opens in Read only mode. Excel allows you to edit the document, but LibreOffice doesn’t, you are forced to save it first.

I often want to do a quick calculation on the spreadsheet and don’t actually want to save it on my computer. Is there a way to change LibreOffice’s behaviour?

Thanks
Sanjay
