Alert SacRT

I would love to be able to change the sound of the alert to like the choo-choo sound in my iPhone or a train bell so I can change the sound of the alert. Like if a sound of a light rail train was recorded, I could use that for the sound of the alerts. And it makes more sense that way.

I travel only by gold line and would like to filter out messages for blue and green line or view all messages if I so choose to. . Also, I would like to delete all messages or messages that are older than the one I have selected, etc. Also I have my iPhone using dark theme and I am unable to see what I am typing because your app is showing white text on white background. I had to type all this up in Notes app and transfer it over here.

Can't find under Sacramento RT, Sacramento Regional Transit, Regional Transit, etc. in the App Store. Had to find under Alert RT but only knew the name from someone else. If I didn't have someone who already had the app I'd be unable to locate. Need to add search criteria App is good with quick response. Wish the other app with train times was still around. Cannot locate that either. Only Zip Pass and I don't need it. :-/
