Conditional Formatting - Highlight SUBITEM column if there are subitems present

I think it would be extremely useful if it could be more visually apparent if there are subitems actually present in an item.
We have a check box column ‘Additional Electrical Required?’, and beside it, a subitem column for the additional electrical elements to be listed if this is in fact the case.
Really easy to look over if it’s all the same colour except for the subitem icon being slightly darker if something is entered. For now, I’ve conditionally coloured the checkbox column (highlighted if checked) but would ideally take away the checkbox column altogether and and just enter subitems right away if there is additional electrical.

Looking forward to updated features.
Thanks!
