Is possible to optimize several outputOptions setting suspendWhenHidden as FALSE ?

I have many outputOptions setting suspendWhenHidden = FALSE

outputOptions(output, "renderui_1", suspendWhenHidden = FALSE)
outputOptions(output, "renderui_2", suspendWhenHidden = FALSE)
...
outputOptions(output, "renderui_N", suspendWhenHidden = FALSE)

This takes a lot of time
Is it possible to make this more efficient?

Didn't found it in documentation but I still haven't tried something like

outputOptions(output, c("renderui_1","renderui_2",...,"renderui_N"), suspendWhenHidden = FALSE)

Any help is appreciated

you can use purrr::walk like so

library(shiny)

ui <- fluidPage(
  verbatimTextOutput("tout"),
  uiOutput("renderui_1"),
  uiOutput("renderui_2")
)

server <- function(input, output, session) {
  output$renderui_1 <- renderUI({
    p("some ui")
  })
  output$renderui_2 <- renderUI({
    p("more ui")
  })
  
  purrr::walk(paste0("renderui_",1:2),\(x){outputOptions(output, 
                                              x, 
                                              suspendWhenHidden = FALSE)})
  
  output$tout <- renderText({
    capture.output(outputOptions(output))
  })
}

shinyApp(ui, server)

thank you
that helps
also testing lapply'ing to the list of outputs to compare.
