I need to be able to quickly and easily create new items. 

Take for example reports. 

I have one org that has a specific report on Accounts that I like. 

I want to copy it to a completely separate org. 

Previously in MM I would just copy over the .report file, update the package.xml so it knows about that report file, load MM and then deploy to my prod org. (Let's forget that TWS can't deploy to prod like MM could, for now - in this case I was trying to deploye to a Sandbox). 

But I can't even do those steps and get TWS to recognise that I have new files in my src folder. If TWS is NOT reading my src folder when it opens a solution what exactly is it doing? 

Is there any way I can do this? I tried adding a new folder, dropping the files in that folder. TWS did not read the folder. I tried creating a new item - you can only create new dev items, not ALL metadata items. I tried adding the new items to the package.xml file - it corrupted my whole solution. 

How do I add new items to my TWS solution so I can deploy them to a Sandbox.
