Can you show a large letter overlay over the list view with the letter of the top-left corner episode/Podcast title name while fast scrolling?

When I'm fast scrolling, it's hard to tell what podcasts are being shown on the screen. Could you put a ghosted (translucent) white letter in large font next to the top of the scroll bar to show what letter I'm on?

Example: scrolling the list of podcasts, a letter pops ups with "A", then when a podcast that starts with "B" goes to the top left corner, it switches the letter to "B"

Potentially also dates for lists ordered by date, etc. (each sorting criteria, show that data).
