Why we are not able to create fields on the FLY when training Form Processing
I was watching this videos https://www.youtube.com/watch?v=3ggCWEymNXI and it showed how we can create fields on the FLY (mainly on this time @ https://youtu.be/3ggCWEymNXI?t=512) while we are tagging the document. But when i tried to create a form processing inside our Power Automate environment >> i will be inside a stage where i am required to pre-define the fields that i will be tagging.. so why we are not able to create the fields on the FLY as shown in the video? is this a feature which is no more available?
here is the page i am talking about which requires me to pre-define the fields:-
This video has been created with a previous version of the product.
Since we added the collection feature (ability to extract data for several documents layouts), we have changed the paradigm asking to define fields upfront in order to avoid inconsistency in data extracted across collections.
