There is not anything currently built into TP Desktop to accomplish this but it is in our feature list for an upcoming release. The idea currently in design is that a setting in TP Desktop would allow the designer to embed a version/revision string that could be displayed in the about form of the device; alternatively somewhere on the entry form by using a special token label.
Currently, our users tend to control this themselves with a static label on the form that they update with a particular revision string for the caption.
Keep an eye out for future releases where I hope we can get this feature implemented.
