Populate subject field from anchor-link, Css ID button

Hi,
I have a contact form on the bottom of the page and a few different buttons on the same page, with in-page anchor links, and all of them goes to the mentioned form.

Is it possible with this plugin to fill the contact form subject field with the CSS ID or class the button is coming from?

If not, is there any other approach you could suggest me to fill the contact form field accordingly in relation with the anchor-link button is coming from?
