Supports needed

Hello.
Im new to creating coasters in NoLimits. I just finished my first coaster. Its a Maurer & S?????????hne X-Car coaster. I know that the whole coaster is too big for the little speed it has but im still learning and it was my only way of getting it less bumpy and remove almost all of the G-Spikes. But however im even worse on making custom supports and i dont want it to have the NoLimits default supports.

Is there someone who wants to help me and give the coaster custom supports?
