Exporting Invoice as .PDF


I’ve made an invoice system in airtable. I now need to export to send to a client.
However I need my invoice to follow a certain naming convention to be able to use for later.
I’ve made a function field to takes care of that.
I can PDF from the print prompt and name my document, but I need to copy/paste the name from my function field every time.
Is there a way to automatically name my PDF based on my function field?
