Dynamic field in Steps slide theme Portland

Hello,

I have installed the theme Portland for my Shopify. I have started to prepare the whole default product page. At one place on the product page, I have a Step slide part. It’s possible to add a dynamic source for the title and the image but not the text field. Is it possible to add this dynamic filed also inside the text field without breaking everything ?

In the attached picture, you may find the edition panel with every field have dynamic source expect multi text part.

If it’s not possible, I will do a template by brand but it means in case of change I have to go on every template to change it.

Thanks in advance an wish you a good day !
