Change form ID

Hello,

I have for example the following shortcode: [contact-form-7 id=”15194″ title=”Form de contact 1″]
Is it possible to change the form ID? Or this is something automatically assigned and cannot be edited later?

Im using the same form within the same page (one at the footer, and another one on a popup). I would like to differentiate them. And i think the FORM ID is a good way to know from which form was used by the user. And also it would be good to assign a “readable” ID for each form .

Thanks!
