Exposing transform 2d matrix prevents widget use

I've got a number of images that share the exact same transforms. Using the transform widget in 2d view for my scenario is the fastest way to position and scale multiple images. Instead of manually updating each one I want to instance their values. I setup an exposed parameter then duplicated the transform nodes. However, the widget is no longer useable even if I click on "Edit in 2d view".  

I couldn't figure out a way to expose outputs from a Transform 2d so they can be daisy chained using custom inputs, so I assume exposing to the main graph is the only method to instance a transform 2d? Below is my instinct on how this should be possible.
