There is no GUI interface in ahsay acb client to make a seedload, but you can easily make the seedload through editing/running a Batch file thats located in:

C:\Program Files\AhsayACB\bin\SeedLoad.bat

open the file in notepad and change the following value:

SET OUTPUT_DIR=C:\Seedload

to where you like to save the seedload.
save the file, and run the file, it will start to make the seedload
