Yes! Start a new, basic park, then click on the coaster tab, and then click the import coaster button. Navigate to your NL1 coaster and select. It will then place it in your park (usually in the middle), but you can then move it to where ever you want, and add even more NL1 coasters that you wanted to ride. Careful when moving them that you don't drag any of the roll nodes as this will mess up the banking for the whole ride, and sometimes if you rotate the coasters this can also make for jerky/wobbly banking in some areas.
