Indicator Line Height - Add 0 Line height to remove

Hi,

I think this could be a quick way to edit already built indicators, but would be a nice addition.

We can set the line height of some indicators, but the values start at 1 going up to 5.
But we have no way of removing an indicator line from a set pack.

I would like a line height of 0 to be added, so that we can remove this option if not needed to be viewed on chart.
Example:
Average Directional Index.
If we only want to see the ADX value, we should be able to set a line height.
But if we do not wish to see D+ or D- values, it would be nice to have an option to remove these from the charts.

This is one example, pick whichever indicator and the same applies if they use more than one line on the chart.
