Allow option to link to workspace, instead of repos
By linking to a subfolder of an existing workspace and maintaining the copy there, it would be possible to allow an external program to handle the actual commit, and by that including the SQL changes into a bigger revision
You can link to a folder by creating a custom config file and leaving the options blank. This will just script out the objects to the folder, but not actually commit them.
