Is it possible to combine different line type S etc to different requisitions types or PO types

1) Is it possible to combine different line type S with a Y inventory interface, then and L3 is 3 way match ( with B inventory interface) to different requisitions types or PO types.  Both of these scenario’s would allow us to combine material ordered for inventory and material ordered for just in time repairs onto a single purchase order.

2) also can we combine S with L2 is 2 way match with ( with B inventory interface), so then the freight line or the environmental charges can be entered at requisition or at PO itself.

In my opinion I believe JDE standards allow us to enter different line types in a Req and PO, the only difference is that we have to remove the default Line Type from the P4310 processing options.
