Couple of questions about making a depth gauge.

My HUD has a depth gauge on it. Its a progress bar that fills from the top to bottom to show how far down the player has gone down.

I’ve got it working to fill in to show depth, but i would like to add a little icon of a person that follows the fill line for a bit of extra flair, if possible. If not, its not a big deal.

Also, is there a way to have the bar partially fill up and keep a reminder of where it was. To keep a record of how deep the player went in case they died?

Thanks in advance.
