Feature request: Informative caption when using `tbl_regression()` with `mice::mira` about gtsummary HOT 2 CLOSED

Dear @ABohynDOE , thanks for the post. That is an interesting idea.

First, I just want to point out that you can add footnotes from within gtsummary, and it will be included whether you use gt or flextable output (see example below).

Regarding the request: hmmm, there is certainly good information that could be reported alongside MICE regression models. I think that statement applies to all models, actually. But I question whether it needs to be included by default, since it's possible to simply update the table with any additional information you'd like.
🤔

set.seed(1)
imp <- mice::mice(iris, m = 2)

# Fit a model for each imputation
mod <- with(imp, lm(Petal.Width ~ Petal.Length))

gtsummary::tbl_regression(mod) |> 
  gtsummary::modify_footnote(label = glue::glue("Results pooled from {mod$call1[[3]]} imputations"))
#> pool_and_tidy_mice(): Tidying mice model with
#> `mice::pool(x) %>% mice::tidy(conf.int = TRUE, conf.level = 0.95, exponentiate = FALSE)`

Dear @ddsjoberg, thanks a lot for the quick answer ! I wasn't aware that modify_footnote() could add new footnote, that's really interesting !

Given this new information I don't think that adding the caption by default is a good idea because, as you mentioned, it opens the door to doing it differently for each possible model that can be passed to tbl_regression().

So I'll stick with your solution and close this issue. Thanks for the help !
