Incorporate Guide Search into Flow Builder

We would love to see a way to incorporate the Article search functionality from the Classic  Web Widget into Messaging and the Flow Builder tool.    We have a vast knowledge repository and a wide array of products, which makes it extremely challenging to map out all of the possible inquiries into the Flow Builder.   However, at the same time, we do have some more repetitive inquiries which could benefit from a pre-determined end point, which the Flow Builder provides. 
If "access guide search", for example, was a step that could be added into the flow builder tool, that would give us the ability to present either a wide or a targeted query into the widget, depending on need.
