Add/Augument timetable with additional date

I have a timetable T1 like

date                         visitors
--------------------------------------
January 1 2020               40

I want to populate another row with

date                         visitors
--------------------------------------
January 1 2020               40
March 1 2020

Then I want to retime and fillmissing. Thus I need to know how to assign 'March 1 2020' to this timetable T1.
