However, to manually (I mean, here, not to use LilyPond's auto-beaming
functionality for subdivide beams, because even till now I still
cannot be clear how subdivide beams in auto-beaming works and trying
relevant commands often cannot bring me to the desired result) create
subdivide beams, in the example above, you must say `\rb` and `\lb`
before and after the last note of each subgroup, respectively. This is
not quite convenient and not straightforward, because it isn't quite
intuitive for code readers to identify that it refers to subdivision.
my desired effect is just using one command like `\sdb` (abbreviation
for subdivide beam), and transform the above code into:
example = {
\relative c' { c16[ d e f \sdb g f e d \sdb c d e f \sdb g f e d] }
}
So, is it possible?

I don't know if a manual command that does what you want is even
possible, especially if no number is provided (assuming in the latest
development version). You could maybe define `\sdb` to take 2 arguments
(the 2nd being the note itself) as a trick, though this is not my area
of expertise.
Try this (assuming if you are still ok with providing the subdivision
depth):
sdb = #(define-music-function
(n m)
(integer? ly:music?)
#{ \set stemRightBeamCount = #n
#m
\set stemLeftBeamCount = #n
#})
example = {
\relative c' { c16 [d e \sdb1 f g f e \sdb1 d c d e \sdb1 f g f e d] }
}
