Form submission as activity is tracked globally automatic, but if you want to tie it to some conversion, you will have to do it one by one, unless the form is been added via a web part on a reusable template, then all pages using that template will be tracked with one configuration, and new page created using that template will automatically be tracked with the same conversion as well.
If different forms are added to each page using widgets, or those page use ad-hoc templates, you will have to do it the hard way.
