Is there a way to resize natively the text as we can do with images?

I have created a master component where I define the layour and proportion of different elements (image, text, button, …). I have a set of different size “slaves” components that resize the image, button, … according to their size. However, text does not resize. If I have a narrow “slave” component, the text does not shrink, or if I have a bigger one, it does not grow.

I would love to be able to do that, as now I have to do this by hand every time. Is there a way to do it or are there any plans to have this feature soon?
