Not sure if this is something XD would do or Protopie.

Currently when exporting to Protopie there are no options aside from which artboards to send. When the elements come over they are all flattened to bitmap images. Protopie seems to have almost the exact same element types as XD but they currently do not link to one another and there is no option to select bitmap or text/editable vector. This is great for text since it means users won't need to have the fonts installed to view the prototype correctly on mobile. But it is a serious issue when I need to change something like a button state, also there is some text which I would like to remain editable in Protopie for use with the text response.

I would love to have the ability to "Tag" elements in XD for Protopie import as flatten or retain, the default could remain as is but some fine tuned control over the elements in Protopie would be great for advanced users.

Example: I have a button in XD, I would mark the rectangle as retain and the text inside as flatten so when it comes into Protopie I can play with the color, shape and size of the rectangle but the text will be prepped for the mobile export.
