Advocate IQuery Editor preview reloads all previous steps after an edit even if nothing changed
I have a relatively complex PowerQuery with a few queries that merge. Every time I make any change in Query Editor it reloads all previous steps. As these come from many sources, it can take up to 5 minutes before I can make any more edits every time. For example, adding a Cutom Column with a very simple formula of "= 1", it begins reloading all previous steps. As nothing has changed, this slows me down when using PowerQuery Query Editor considerably.
Is there a way to change a query's setting so that preview doesn't automatically rerun all previous steps in all upstream queries when there is any downstream change?
I haven't seen anyone post on this exactly, which surprises me, as this is quite an issue for how I use PowerBI.

Sorry, marked as solution at first, but this issue still prevents me from using PowerBI as a tool for data munging. If it takes 5-10 minutes for Query Editor to refresh and reload all data that hasn't changed before I can add another step, I may forget the next few steps I had in mind. This reloading of all previous data may save on memory, but to prevent preview and additional edits until all previous steps are re-run makes Query Editor unusuable for my data munging workflow.
