Date Field formatting

I’ve discovered that if a pdf field has a date formatting that is not yyyy-mm-dd, then the posted form date is not filled in (posted date is yyyy-mm-dd). I realise the obvious solution is to modify the PDF, however I wonder if it might be possible for your service to recognise the field formatting and perform the conversion?
To be clear, if the date is posted as 2021-07-30, and the PDF date field format is to display as dd-mm-yyyy, then convert the date to 30-07-2021 before passing it the the form processor?
