I have a finance spreadsheet I created for myself to plan my household
budget where I have a row for every day of the year. Sine some days
nothing happens amongst the days I am planing for I created 2 views. One
which displays all the rows and a "part view" which hides the rows with
no activity. As the year goes on and I plan further down the sheet I'll
want to edit the "part view" so that it includes further rows which will
be hidden. How do I do this? When I go to View/Custom View it only
gives me the option to Show, Close, Add or Delete a view? Would I have
to delete the view, make the modifications and read it - is there any
easier way?
