The process can also be automated. From the Help text:
/~PSPDF when used in conjunction with the /u, /p, /d and /e parameters, allows DocStore to open and run the Process SoftPDF to DocStore function.
Note (after a conversation with Chris): This will slow down again when AR and IN 9.3A ship as the transactions will need to be attached there. But once that is done, those modules will be writing to DocStore and you shouldn't need to run Process SoftPDF again. In the interim, you only need to run the function when you want the documents attached to the
posted transactions in Ledger.
