Controllers for shapes without drivers?

Hi everyone!

I have a silly question :

**Context : **
I render most of my animation in Sheep It. Sadly, they don’t support drivers. I know they have their reasons, but most of my rigs uses drivers. Particulary for the shapes

So, my question is : do you know if there is an other way to link a controller to a shape that is compatible with sheep it?

If not is there a way I could create a button on my rug that would convert all drivers in animation key?
