flat file connection in a stored proc

hi all ,

i have a flat file and i use a flat file connection manager and load the data from flat file to a table. everythings fine....but the problems is , the flatfile layout keeps changing every now and then like adding column increasing and decreasing  Len of the columns etc. so i have to go in to he package and modify the connection every time there is change in layout ... redeploy the packages. i would like to maintain this in a stored proc and pass it to connection manger and use this layout to grab data from faltfile and load into table. is it possible how do i do it? please share.
