changing the CRM TPM pricing Guidelines BRF

Hi Experts,

We have a need where in we need to modify the pricing guidelines in CRM TPM scenario. Following below are my requirements.

1.  The standard system when creates the pricing guideline records/rules it only do it based on key as  sales area + start and end date. then against this we can create multiple records of products, with each product with a price as MIN or MAX etc.  We want to create these records of products along with Customer group 5 record. e.g

Sales Org = 0 527672   DIST CHNL = C1 DIVISION = 02       start date = Jan1   End date = Jan10

Product = 1234  CG5= D12   price = $2

2.  We want to compare this $2 against a spend type  which could anything between 1 of the 5 spend which user can select.

Please guide how to achieve this change via BRF.
