Display Starting Position on Dashboard

I have a hard time remembering my starting position and would like to display that on my dashboard. I can use Position, but that will change. I'm unable to find any other telemetry value I can use. Is there a way to have a text box display the initial position value, and lock in that value so it never updates during that race? If that makes sense. Probably doesn't matter but this is for Grid 2019. Thank you.
