Hi there,
I’m sorry you ran into trouble here. Though Caslon and Adobe Caslon Pro are very similar and they are essentially entirely different fonts as far as the computer can tell. Caslon isn’t owned or produced by Adobe but Adobe Caslon Pro is. Both of these fonts are digital versions of a very classic typeface called Caslon of which there are many variations.
I’m sorry we can’t automate this for you. I hope this shed some light on the situation.
Let me know if you have any further questions.
Thanks,
Harshika
