automate routine functions with VBA-like script

Interesting point about high performance with hundreds of millions of rows but circumstances where the model has a negative effect. I'll look for some design tips and revisit my model.

Back to my original question about VBA-like automation functions using a specific example: a report has ten pages, one for each floor of a building, and each page includes a floor plan created with Visio and the Visio Visual. Each page also includes a collection of slicers and other visuals. I'd like to make the same change, perhaps a formatting change, to each visual of a certain type on each page. Describing this in VBA-like pseudocode:

for each page
  for each visual
    if visual.name = "ABC" then
      <make changes>
    end
  next visual
next page

Possible to script this for Power BI? From what I've heard so far, I'm guessing the answer is no, but thought I'd ask.
