Sure, it should be possible.  Since you post this on the rrd-users list I can
safely assume you're using RRDtool.  Without changing *anything* in your
current setup you can start generating some sample images and evaluate them.

Example (you fill in the "..." part)
rrdtool graph /path/to/image.png -a PNG --start end-24h --end midnight \
DEF:link01inbound=/path/to/RRDfile01:ds0:AVERAGE \
DEF:link01outbound=/path/to/RRDfile01:ds1:AVERAGE \
DEF:link02inbound=/path/to/RRDfile02:ds0:AVERAGE \
DEF:link02outbound=/path/to/RRDfile02:ds1:AVERAGE \
...
DEF:link26inbound=/path/to/RRDfile26:ds0:AVERAGE \
DEF:link26outbound=/path/to/RRDfile26:ds1:AVERAGE \
CDEF:totalinbound=link01inbound,link02inbound,...link26inbound,+,+,+...
CDEF:totaloutbound=link01outbound,link02outbound,...link26outbound,+,+,+...
AREA:totalinbound#00CC00:"total inbound " \
GPRINT:totalinbound:MAX:"%6.2lf %s" \
GPRINT:totalinbound:AVERAGE:"%6.2lf %S" \
GPRINT:totalinbound:MIN:"%6.2lf %S\n" \
AREA:totaloutbound#00CC00:"total outbound" \
GPRINT:totaloutbound:MAX:"%6.2lf %s" \
GPRINT:totaloutbound:AVERAGE:"%6.2lf %S" \
GPRINT:totaloutbound:MIN:"%6.2lf %S\n"

You may want to read my tutorial, it can be found in the distribution
and on the web.

Check the links section of the MRTG FAQ.  There's a new link which points
to helpful cisco information.  Maybe it's there.
