Is it possible to pre-tick a box on a form using a token?

[Paul_Raybould]

Hi.

I've created a form on a follow-up landing page that enables people to specify their topics of interest through checkboxes.

As 'Form Pre-fill is enabled  assumedit would autopopulate these checkboxes with the information we already have on the person but it doesn't.

Is there a way to define whether a checkbox should be preticked based on existing data? maybe using tokens?

Thanks,

Paul
