I would just print the mastered wav when finished, add it to a new session, and automate hi-pass eq to the specific frequency of the bass drop, (random band for example plays in Drop C or C standard so lets say 65.41hz or the nearest you can get passed that) create subdrop in that key, slap it in into the desired part, and have the hi-pass back up as the bass drop fades away.
Most modern bands want their bass drops audible without needing subs though. In that case you need to have the harmonics of the bass drop come up as well. I think it sounds gay though so I don't really know much about that.
