Right now you can only create a pattern in an Application Object that matches onto a single line of text. Once that text goes onto the next line it doesn't work.
For a use case like a trip reservations or logistics trip:
Leg 1 LAX - SFO
Leg 2 SFO - PDX
or
Stop 1 Los Angeles to Dallas
Stop 2 Dallas to New York
There's aren't possible given the current setup and they require a hacky use of Dynamic Variables.
Your idea is now live and open for voting.
