To reset many lists

I use LibreOffice 5.1.2.2
with SO Windows 7

On a file calc I have many lists,
drop-down menu contained in individual cells,
for each list a cell,
every drop-down menu contains 10 numbers, from 0 to 9
since I have many list I’d like to make a simultaneous reset for each list
(for reset I intend the number 0).

Thanks in advance for your time
