Arcade-style scoreboard

Hello!

I’m building a small arcade-style space shooter… Got almost everything to work fine/perfectly.
One of the last things to implement is a menu where I can set the player name so after the player dies it can add it to a leaderboard. For now, I have an editable text block to set player name to my player blueprint and it’s working just fine.

But now I want to change it to an arcade-style name input with 3 characters you can scroll through with a gamepad using up and down and a button to set the player name.

It should look something like this:

I did some research and can’t seem to find anything remotely close and I was wondering if anybody here can help me in the right direction.

Thanks in advance!
