As voltage drop by different length and grade of power cable, this maybe not as ideal as digital communication. Just my opinion…

I do not think you need that second setting. The application can regulate the current by itself by adjusting that feedback or voltage setting signal. Less voltage means less current.
Unless you are talking about single fault conditions; in which case you have a similar problem when using digital communication.
