Adjust setView() for each group

[aloboa]

I need to open the map with a relatively wide extent, but then some groups would
need a more zoomed view. Is there a way to define specific setView() for different groups?
For example, in this example:

library(RStoolbox) #for the example satellite image
library(terra)
library(leaflet)
B4  <- project(rast(system.file("external/landsat/LT52240631988227CUB02_B4.TIF", package="RStoolbox")), "EPSG:4326")
ext(B4)
leaflet() %>% 
  setView(lng = -50.5, lat=-3.4 , zoom = 9) %>%
  addTiles() %>% 
  addProviderTiles(providers$Esri.WorldImagery, group = c("Satview", "Landsat")) %>%
  addRasterImage(B4, group = "Landsat") %>% 
  addLayersControl(
    #baseGroups = c("Satview","OSM","r1","a"),
    baseGroups = c("Satview","Landsat"),
    options = layersControlOptions(collapsed = FALSE, autoZIndex = TRUE))

I would need a "zoom to layer" behaviour when selecting the group Landsat.

You could just use something like this:

library(leaflet)

df <- st_as_sf(atlStorms2005)
leaflet() %>% 
  addTiles() %>% 
  addCircleMarkers(data = breweries91, group = "breweries91") %>%
  addPolylines(data = df, group="atlStorms2005") %>% 
  addLayersControl(
    baseGroups = c("breweries91", "atlStorms2005"),
    options = layersControlOptions(collapsed = FALSE, autoZIndex = TRUE)
  ) %>%
  htmlwidgets::onRender("
    function(el, x) {
      this.on('baselayerchange', function(e) {
        if (e.name === 'breweries91') {
          this.setView([49, 10], 8);
        }
        if (e.name === 'atlStorms2005') {
          this.setView([40, -50], 4);
        }
      });
    }
  ")

Yes!
The behavior of this code is what I am requesting, but the htmlwidgets code is too involved.
What I am suggesting is a Ruser-friendly function
that would do that behind the scenes.

Anyway, after trying, I am finally not using this tool in my map: Having a "zoom to layer" behavior always active (anytime the layer is selected) is often inconvenient. For example, if we want to display Satview for the zone of interest once we have selected Landsat, the Satview button brings us back to the initial view. We would need a second button next to the one selecting the layer so that the user can "zoom to layer" if needed, but not always
