Thanks for reaching out to us about this PDF preference for invoices concern, @parind-phadte.

Upon saving the invoices, there is a default file name assign to each entries. At the moment, there isn't any setting to update this unless you change it manually when you save the entry.

Here at Intuit, we aim to understand better our customer's business needs within the software. This is why we welcome product suggestions to help improve our products and services.
