No. As @bowesmana already told you - the -d "something" option sends the data you specify on the command line. If you want the data to be read from the file you have to specify it as the source for the POST data with the -d @filename option. And there is no "templating" you just specify raw data to be posted. So it will not work like "get a part of the data from the command line and iterate some file's contents over it". No - if you want something like that, you have to implement it manually (bash scripting, python, PowerShell, whatever).
