Not sure what you're asking.  I think you're
asking whether you can about doing something
like what I did in help-fns+.el: let a single
option value specify both:

1. Either a list of manuals or a value that means
   use all manuals present.


2. Whether to do <something>.

In my case, #2 is whether to search the manuals
specified by #1 before creating the button, so
the button either (a) takes you directly to an
Info Index buffer (menu) of the relevant links
or (b) searches the manuals and produces such
an Info Index buffer of links when you click it.

(a) Takes the time to compute the menu before
showing *Help*, which is a waste of time if you
never click the button.

(b) Saves that time before creating *Help*, but
spends it when you click the button.

TBH, the approach in help-fns+.el is not very
satisfactory, because of the time to compute
the links (either way).  But that's what that
particular defcustom is about.

In Customize, there are two things to customize:

1. "Which Manuals:" which has a `Value Menu' that
   lets you choose between "Specific Manuals (files)"
   and "All Manuals".
   For the former, the type is a repetition (`repeat')
   of type `string'.  For the latter, the value is the
   symbol `all'.

2. A toggle button, "Search Before Creating Button?"
   The type is `boolean'.
