Hello Gregory,
Currently, a similar result can be achieved only using a custom CSS and code on the window resize event.
I made an example which is just demonstrating the general idea how this can be achieved(for better results test in the non-fullscreen mode of the Dojo):

If additional assistance is needed with the implementation, I can recommend our Professional Services team which is specialised in providing custom solutions and features:
