separating tracks from a continuous mix?

I am a dj new to audacity and am looking for a way to separate a continuous mix into numbered tracks. The program I record with does not have an option to do this, so my finished product is a continuous 60 minute track “1”. I can import it into Audacity and apply filters and such, but how do I place “cues” or “markers” to separate the tracks where I want them to have tracks “1-60”(example) that u can flip through on the cd player? Help Please?
