This is how I do it if the game or launcher doesn't have a native option for it.

You can do the same through command line but the tool above makes it easier.
1. Cut/Paste the Bioware/Save folder wherever you want
2. Right Click on the Bioware/Save folder in its new location and "Pick Source"
3. Right Click in the folders original location (in "Documents") and click "Drop as... Junction". Make sure you go the actual Documents folder and not the Documents "Library" if you are using Windows 7/8, otherwise you won't get the right context menu to drop a junction.
