PO release based on Classification

Dear Experts,

Hi experts,

Our team has configured PO release procedure, in that they used Order type(BSART) and Material Group (MATKL) as the characteristics for the Class that is used for that group. FYI in the system there is only one Release group and two release strategies, For both strategies document types are common. First strategy contains the Material groups starting from "0001" to "0075" and second strategy contains material group from "0076" to 0086" which are capital goods. As the client requires that capital goods need to be approved by 4 levels instead of 2 levels as in case of normal material group.

Now my question is whenever we make a PO which consist of the materials of same group then onnly release strategy is attaching to it, i.e. all materials in PO should be of same material group. If atleast one material has different group then release strategy is not attaching. How to tackle this type of situation??
