Can I change the location of the "Submit" button from the last page, to the first page of an uploaded PDF?

Can I just upload an existing fillable pdf form that id like to use?

My question is in relation to the above question thread.  I can import my PDF, but would like the submit button to show on the first page, not the last.

I found I can move the button on the form using Adobe Pro, cut and paste the button from the last page to the first.

For fillable PDFs you can edit them using a PDF editing software same as the one you've used or also foxit phantom
