Need to have a all-time stop loss for swing trading!

I am facing a problem as a swing trader that is I am unable to keep a watch on my stocks all the time because more important things pop up and I always have my stop loss ready but I am unable to execute it while I am busy in other things as a lot of traders are also job employees, they may also have the same problem.

I want an order process which will work like, we will buy stocks on CNC and place a stop loss of 1% or 2% on the same time while I will be executing CNC order and that stop loss need to be active a whole week when market opens. Or tell me is there any way to make this kind of stop loss order.
