Change/edit element ID

Is it possible to manually change the id of an element to something of my own choosing?
At the moment I am stuck with the id’s auto generated by bricks, I would like to change some of these to something a bit more meaningful and understandable for myself, but I cannot see how to do this.

Thanks.

Hover in the Element ID box and you should see some icons appear. Click on the pencil one ( Rename Element ID )

I don’t seem to have that option - when I hover the icons do not appear for the ID.

They do when a class is in the element box and I can edit that, but no option to edit the ID.

This is the same on my own site and the try bricks playground.

I don’t know if there is something in the settings I have changed to disable this or that I have to set to enable it?
