Numbers Autocomplete between files
Hi there, I love the autocomplete function in a sheet between cells, so when I enter data whether it's text or numbers, I will know if I've entered the same info twice in a sheet.... this is great for invoicing - now my question is, after so many invoices (separate files), there could be duplicates between files and I would like to know if there's a way that when I create a new file (invoice) that autocomplete will continue or show up? so that when I enter data in a new sheet it'll give auto suggestions....is this possible? I can understand that I can create 1 file with many sheets inside - but was wondering if there's a way to have that autocomplete data work across all the files especially when creating a new one (these are all created from a simple custom template btw)
Thank you all in advance for any insight on this!
