Global modal dialog

Hi Webflow community!

I have several call-to-action buttons on my website which trigger a modal dialog (where people can download a free PDF). All these modal dialogs are embedded on the respective pages and are hidden before they are triggered.
I would love to have a button in my footer section where people can subscribe to my newsletter.

My question:
Is there a possibility to trigger some kind of “global modal dialog” or do I have to embed the modal dialog box „hidden“ on every page - since the footer is shown on every page.

Thank you for your help and best regards
