Compiling a list of static targets without tar_read_raw?

Question

I have a sizeable set (n ~= 20) of static targets of which I need to load a large number of different subsets for different analyses. Currently, I'm using an object loading function that wraps tar_read_raw for this, but this breaks my pipeline's ability to track upstream changes for any code that depends on this object loading function (right?). E.g.:

load_objects <- function(names = c('A', 'B')) {
  purrr::map(names, ~targets::tar_read_raw(glue::glue('obj{.x}')))
}

Should I specify any potentially relevant subsets into new targets using tar_combine or is there a more flexible way that doesn't require me to define new targets upfront while also allowing targets to track changes to the upstream static targets?

Thanks :)
