Your best bet is to follow the advice I posted on my blog:
http://frameautomation.com/run-a-script-in-response-to-a-command/
Install the "test" event script that will display an integer whenever you perform a function. Try applying paragraph formats in various ways and see if you get a consistent number. If you do, you can modify the event script to test for that particular function number. Then, when that number is triggered, test the paragraph format of the current paragraph and apply the appropriate condition format. If you detect a different format, you may want to call a function that will remove the condition format if it is applied. Please let me know if this is not clear. Thanks.
