Inventor (File > Vault > last button) is a "Check in Project" button. I really like this for checking in large amounts of new templates and non-Inventor files. However this must scan your ALL the files in your project before the dialog comes up (which could take hours). To work around this delay I MOVE all my other files outside the project folders "Check in Project" then I have to move them back correctly and remember to do so.
AutoCAD has a Vault "Check in Folder" toolbar button. I would like the same/similar for Inventor. It should function just like "Check in Project" but only scan the selected local folder.
BONUS POINTS: After the folder is scanned, allow deselecting files and folders or filtering file types. Clearly this would have to carefully confirm file references.
