OCO Order Type and a Finite Horizontal Line with Price

Please, I would like cTrader to have the OCO order type - that is, One Cancels the Other (Another). I would also like the platform to have a finite horizontal line for drawing horizontal lines of a user defined length. I sometimes use the SHIFT + trend line button to achieve a finite horizontal line, however, the finite line does not display a price as a horizontal line does when I right click it.
