It's not possible to get clouds lined up.
But what you can do is make very wide thermals, or a lot of thermals, by altering the flightplan in Notepad (kladblok).
This is a flight I did once with BRA and SOI, in std class 18m. If you don't fly too fast you don't need to circle.
But you can experiment with the weather yourself, open a flightplan in Notepad, and change the parameters.
If you make the thermals too strong, your wings will brake when entering.
