Simple request. Can the scripting function
$initials(text)
be expanded so that there is a second, optional variable much like $swapprefix()?
In this case the second variable would choose whether the function returns the first letter of each word
OR
the first letter of each word AND the NUMBERS of the text.

So
$initials(text,*optional input of 0 or 1 for desired option)

example:

album: Some album volume 20
input: $initials(album,1)
output: sav20
