Necessity to create some descriptive flexfields for the BPA

Content (please ensure you mask any confidential information):

Hi to all, I need to know how I can manage the descriptive flexfield for the Blanket Purchase Agreement. In particular, once I started to create an agreement, after selected which type of agreement I want as result of the procedure, I have the necessity to have some flexfields in the headers section once choosen the BPA format. I've searched in the setup and manteinance working area, but I haven't found anything about it. Could someone give me any advices on how to perform these managing stuffs? TIA
