Hey Tobi!
There isn’t an option for adding in the description to that dynamic product block that you drop into the editor but depending on your flow, you could show/hide sections you build out with recommendations you hand-select based on their conditions.
Great examples of how to use that feature here:
So let’s say your flow is based on cross-selling them into different items, you could show/hide certain recommendations based on the trigger data of what that first purchase contained. And then you’d be able to fully add in product descriptions etc since it will be a section you manually built! Just one work-around but more manual.
