There is no work around. Field are pre-populated via GET or via PHP. You can write code to accept that post and then use the available PHP hooks to take that data and pre-populate the fields.
It isn't much different than the get, just takes a little more code as you need to write some code that does a request on the post to get the field values and then pre-populate the database fields using PHP. There are hooks to pre-populate fields. Do a search for pre-populate fields dynamically, pre-populate field, etc. and you will find code snippets for the hooks to pre-populate a field.
Writing code to take the post data and pre-populate the fields with it is going to take far less code than it would take to create the whole form from scratch, store the data, etc.
