How to minimize post-run time after a SEC run?

Hi all,

I am new to HPLC and am using our Agilent HPLC 1200 series with ChemStation software version C.01.07.

I am using Size Exclusion columns, meaning that after I run my sample (approx. 14 minutes) the run is done and I can directly proceed with the next sample. However now right after I run my sample for 14 minutes a "post-run" takes place, where the column is washed with buffer again for another 14 minutes. This wastes both time and buffer, so does anyone know how to shorten or even better eliminate this post-run time? I have been looking into post/run macros but none of the commands seem to be directed at what I am trying to do. 

Thank you very much for your advice and help!

All the best,
