Create draggable elements?

Is it possible to create a study that includes horizontal lines that you can click on and drag?

Obviously, you can use drawings instead. But my study involves calculations based on these lines. So, I’d like to be able to drag the lines to the locations that I want and then have the study use their locations in the calculations.

Currently, I have the levels as inputs instead. That’s a solution but not a great one, because it’s much less efficient to have to click on the gear icon and go in and adjust the inputs.

Please let me know if you have any suggestions. Thanks!
