I ran into this problem several years ago, with a Leica sp1.  At the 
time, Benjamin Matthieu wrote up a set of routines that import the 
files, allowing you to select which ones you want.  The set has not 
been made publically available because they are still somewhat crude. 
 However, I would be happy to share them.

My file structure involves a file name of the form:  
r5 6-8-04_Series002_t00_z002_ch00.tif  

in which the channels switch at each z level.

Mattieu's plugin has an option called : time proj.  This reads the 
selected channel, and then for each time point, reads all of the z 
positions into a temporary stack, and then does a Max projection of 
the stack.  That projection is then added to a new stack that grows 
with each time point.  The end result is a single stack in which each
image is the max projection of the images of a "single" time point.

The process is quite slow, since it involves reading and writing a 
large number of images.   

A major problem with these routines is that they do not insert the
calibration data into the images.  You do that by clicking on
"parameters", and entering the data manually into the properties 
fields. 
Also, when you select a file, you have to reclick on it to cancel.  

Nevertheless, I find them quicker than the LOCI routines, and they 
are sensitive to sequential scan records.
