Do something only that last iteration of loop

I have a script with logic like:
Code:
my_function()
{
if [ $2 ]
mkdir $1
mkdir mydir_${2}
else
do something else
fi
}

read in list of items
while read list 
do
my_function $list `date`
done

so basically it will make a directory for every name in the list and create a directory with the date appended (which I only want to do once). What I want to know is how do I perform the line "mkdir mydir_${2}" only once? This is not the script itself, so this example it a bit silly, but the logic is there, I want to iterate through a list and call a function with each item in the list, but there is one element in the function that should only happen once.. Assume that the argument $2 is something that will not change through each iteration, so I do not want to repeat the process doing the same thing over and over. Is there a better solution than to create another function and call it? There is a reason that I dont move this line out of the function, but it's difficult to explain without posting my company's intellectual property.

MU-MKDIR(1)                                                   General Commands Manual                                                  MU-MKDIR(1)

NAME
mu_mkdir - create a new Maildir SYNOPSIS
mu mkdir [options] <dir> [<dirs>] DESCRIPTION
mu mkdir is the mu sub-command for creating Maildirs. It does not use the mu database. With the mkdir command, you can create new Maildirs with permissions 0755. For example, mu mkdir tom dick harry creates three Maildirs, tom, dick and harry. If creation fails for whatever reason, no attempt is made to remove any parts that were created. This is for safety reasons. OPTIONS
--mode=<mode> set the file access mode for the new maildir(s) as in chmod(1). BUGS
Please report bugs if you find them: http://code.google.com/p/mu0/issues/list AUTHOR
