Gather all attribute names and values from a flow

Content

I doubt this is possible but I will ask anyway.

We create a configuration string (through a recommendation rule) of all of the attributes in each flow that lists all of the attribute names and values. If we add a new attribute, or remove an existing, we need to change the recommendation rule.

My question is there anyway to automate this?  Such as a function to automatically gather all of the attributes and values?

Thanks
