Importing data

CRM2016 on premises

Hi,

I am looking for advice and suggestions

I have customers that send me text files that I need to import into a custom entity as a complete file as I have custom workflows to read that file and process it internally.

I think I can set a mapping to import the file, but I would also need to add 2 manual inputs which change each time a file is imported.

Is there a way to put an input box on the import data, or would I need to look at creating a manual workflow to handle all of this

any suggestions would be very helpful
