CAN YOU RE-PROGRAM THE L6C SP PARAMRETER LOCATION SCREEN TO INCLUDE LETTERS SO WE CAN SET UP MORE THAN 99 UNIQUE SP ACCOUNT#'S

We need to be able to set up more than 99 different SP LOC parameters (L6C) now that SP is our 1st call wholesaler and the HP Big Deal program has changed to allow ONLY 1 UNIQUE CUSTOMER TO 1 SP HPBD ACCOUNT# I need to set up separate L6C parameters for each unique SP account# so that we can just change the location at the main DDMS TEXT main menu and enter a PO# and transmit it, and not have to change a bunch of individual parameters every single time we manually transmit a PO. we manually transmit for 'hold for backorder' accounts; for every SP HPBD account# we have we also have an HPBD BACKORDER account. So at this point we have nearly 70 unique SP accounts and I have set each one up under its own SP parameter location and I realized that you can only enter numbers, letters will not populate the location field and so we need more. can you reprogram that field to allow letters? that would provide us with endless parameters I can set up to represent each account# and then my team doesn't have to remember to change the backorder flag or the source complete flag or the DC location,. etc every time they manually transmit backorder PO's or any time the ASB errors and we have to manually transmit a PO that's already been created, we can't use the 3rd screen of the ASB call to manually transmit a PO. With HP having such strict rules for how we transmit and we can lose our HP Big Deal status if do not comply we simply need to set up more SP parameter locations!
