Hi all,
I know this is a strange question and probably will not have an easy answer, but I thought I would try anyway since just about everything else I have ever asked here has always been resolved by all of you:))

We have moved over to full pagination now along with our redesign for our newspaper...and have also moved completely over to InDesign. When we import our classified listing into InDesign and apply all the styles...everything works perfectly except for ONE thing which is causing us a lot of extra time. For the majority of the listings, we need to make all words before the hyphen BOLD. This is pretty hard to explain, so let me give an example...say hypothetically speaking, a single classified ad runs as such:
Peachtree City Single Family Home - 3 bedrooms, 2 bathrooms, huge basement. Only $123,000! Call Joey Jones at 123-456-7890.
What we need to do is make all the words BEFORE the hyphen BOLD ....and try to incorporate this into a style somehow. At present we are doing this manually and it is taking a lot of time. The problem is also that there is never a set number of words before the hyphen. I know very little about scripting...is there ANY way I could set up a script to do this for us? Is a script the direction to go in?
(The normal portion of the classifieds is done in Univers condensed...the bold portions will be done in Univers Bold Condensed.)

(Keeping my fingers tightly crossed that there is some solution.....however I have a sinking feeling that there isn't......)
