Subject:Progressively Change Playback Speed?

Is there a way to progressively change the playback speed of a file? For example; I have a recording that was taken from and analog magnetic tape recording. It appears that the speed in which this tape was recorded was not linear. The tape starts at the proper speed and progressively slows down just a little by the end. Is there a way to compensate for this in SoundForge by means of progressively speeding up the playback to counteract this problem? It doesn't appear that you can automate the pitch plugin. Any suggestions?

Effects / Pitch / Bend.

Keep in mind though that this effect is linear, while the speed change of the tape is probably logarithmic. You may have to add a few points somewhere along the way to slightly adjust the line into a semblance of a curve to get a closer speed match.
