Is there any automated way to indicate that flag is repetitive?

I use clap 4.5.36 (latest at the time of writing) and I've found that it doesn't show any indication when flag is repetitive. My goal is to indicate to a user that this flag is repetitive and optional as shown in an example below. I don't like to specify num_args as it wouldn't be readable for a user.

$ prog --flag value1 --flag value2 --other-flag -v -q other positional arguments

I've tried to use just Option<Vec<String>>, add ArgAction::Set and ArgAction::Append. All three possibilities doesn't indicate neither that flag is optional, nor that flag is repetitive.

By searching through code on GitHub, I've found that previous versions of clap seems to indicate ... as shown in doonop project. The project uses ~3.0.0 version of Clap. In following example e.g. ignore flag is defined as Option<Vec<String>> without any multiple* options.

-i, --ignore <ignore>...

There is not at this time; this is being discussed in #4681.
