Inserting identifiable tracks in an imported audio mix

How do you separate tracks whn you have imported an audio filed that is mixed (no pauses) and you want to burn it on a disc showing individual music tracks?
Does Audacity have a way to insert a marker and turn the market into a track that can be named or numbered to be identifiable after exporting it to a burn software? Thanks,_LPs_or_minidiscs_to_CD#split
