Multiple Entries into One Cell

I have a spread sheet that tracks client visits, and am looking for the best way to track multiple visit dates without using a cell for each date. Is it possible to enter a date in a cell, then next month, have another date entered in the same cell creating a drop down for me to click to view all visits?

keep one line per visit, then create a pivot table to view the visits on a particular date..
do not enter multiple dates in 1 cell..
