Add Cumulative value of Profile column in Delta mode as a separate integer above or below profile histogram in Smart DOM

On the Volume delta on the DOM volume column, could you add a Integer with a background highlight for the ASK volume minus the BID volume please, as I have attached 2 images.

2 price levels above, or below the highest or lowest integer.

I use the delta as my volume column, not total volume.

Please note, I do not use charts, only the DOM - To be clear.

I hope this explains my request.

Thank you in advance.
