Wanting to change text on button of first slide of an Engagement.

We were speaking with a customer earlier today who would like the ability to change the text of buttons in an engagement.

The below exampe is the first slide of a guide and in this use case they would like the text to read "Show Me".

At this point I understand that this is hardcoded in the product, but in the future we would like to be able to edit text for all buttons.

Thanks
