Is it possible to generate next task's workflow form in previous handler?

Let's say in first form I ask the user how many files will you attach for this document, and in the next form I put the number of upload elements according to previous answer.

I think is not possible, but in this case the most factible will be a middle task which demands only on file and recursivelly loop across it until will be finished. Each time upload one file is completed by user, will start the task again and will demand a new file ... the usability to end user I think will be right.
