Bulk Updating and adding a Tag in Macros

Hello Zendesk Devs! 

I am looking to update all 17K of the macros we have in our instance and am looking for a good way to do this. 

I've seen documentation on updating the description but what I'm looking for is:

• a way to add the actions of "add a tag" and whatever tag I need associated with the particular Macro

Can anyone help me out with this?
