Cannot find a guide how to edit the conditions for a profile

I am new to takser coming from llama.

I searched with google and looked for tasker tutorials but no success.

I could not even find easy examples how to set up some obvious things like switching wifi off at night.

I finally managed to create a profile with a schedule condition which switches wifi off at night but now I want to change the time condition but cannot find a way to do it except creating another profile and deleting the old one.

I also created a profile to switch wifi off when I leave home.

With llama it was super easy to assign or remove cell towers to an area but with tasker I only find the scan feature which populates the %CELL variable automatically.

Is there a way to see all the cells within a range and then edit the profile condition accordingly?
