Automatically adjusting text tracking/spacing in data sets

[pinotplease]

I have an irregular text path that I'd like to import data onto. I want the path to stay the same size, but I'd like the spacing of text to adjust such that all the text fits on the path for when I import longer data sets.

Any help would be appreciated!

You can't do it. It's a manual control using Tracking. Unless someone who know about scripts - I don't think it's possible.

Figured that might be the case. Thanks!
