Suffixes/Specific help messages for highlighted choices in Select and MultiSelect

[colour]

Hey guys!
This crate is great, however I have a feature request.
I would really benefit from a feature that allows you to add a suffix to highlighted selections.
Let's say you have a list of options;

  [ ] Choice1
> [ ] Choice2 - Lets you do something specific
  [ ] Choice3
  [ ] Choice4

Choice2 is highlighted, so it gives a small custom explanation of what Choice2 does/is. ^
Another example:

  [ ] Choice1
  [ ] Choice2
> [ ] Choice3 - Lets you do some other specific thing
  [ ] Choice4

Choice3 is highlighted, so it gives a small custom explanation of what Choice3 does/is. ^

Either that, or highlighted choice-specific help messages.
Similar to the above ^, but the message text is below, where the with_help_message usually is;

  [ ] Choice1
> [ ] Choice2
  [ ] Choice3
  [ ] Choice4
[Choice2 lets you do something specific]

Another example:

  [ ] Choice1
  [ ] Choice2
> [ ] Choice3
  [ ] Choice4
[Choice3 lets you do some other specific thing]

Or maybe the message text could be above the choices?

Choice2 lets you do something specific
  [ ] Choice1
> [ ] Choice2
  [ ] Choice3
  [ ] Choice4

Another example:

Choice3 lets you do some other specific thing
  [ ] Choice1
  [ ] Choice2
> [ ] Choice3
  [ ] Choice4

Thanks!
