Possible task: generate an order-guide / price-list that pulls all the prices from a master external source, so that prices are always current on re-render.
The source might be a database or just a spreadsheet, or perhaps some rendering from same, such as an XML file generated from the source. Obviously, one could import text insets from a multitude of individual files generated from the source; that seems excessive.
FM9 has only File > Import > File, and File > Import > Object; and > Object is using OLE . OLE is not an answer (for any question, any time, ever).
Writing an FDK extension is probably not an answer.
The Adobe marketing pages seem to have some videos that may or may not address the question, but these are disrespectful of the buyer's time, and don't even run on my usual work platform. There are also some whitepapers with titles that hint of perhaps being on topic, but they are all hidden behind equally disrespectful registration dialogs (I'm logged in already, ADBE, you already have all that info). I wonder if Adobe will ever figure out this marketing and merchandising stuff.
