I have a column with customized data validation (custom formula) that accepts only dates, provided that a few other conditions are met.
How can I add a date picker to the cells of this column? Changing the Format did not help.
Edit: I want to pre-program my cells to have a date picker, just like they would have if the Data Validation criterion were set to Date.
A good workaround is provided by @user0, but I am still interested to know if this is directly possible.
