Best Practice for dealing with WEB API Source refresh on DataFlows

Hey All, 

I was wondering what your work around is for refreshing WEB API for Dataflow. Basically I have multiple queries using difference calls, but all under the same API. So when they refresh parallely, I go beyond the rate limit that the API allows. 

Unlike the desktop file, there is no option for me to disable parallel loading. I am using invoke after and I am giving excessive buffer times to make sure that my data refreshes smoothly. BUt it's really surprising how I can't simply disable parallel loading.

Am I missing something here?

Edit: After a bit of research, it seems this option is not available on dataflows. If anyone has the same issue, https://ideas.powerbi.com/ideas/idea/?ideaid=9f65c4d8-0bf4-ec11-b5cf-281878de4cfd
