Requisition Line context sensitive DFF segment based on Category

Summary:

Can we create a context sensitive dff segment that only displays on the requisition line when a specific category has been selected on the requisition.

e.g.

if an IT category is selected then 2 DFF segments are available to update.

I can see that "derivation value" of categoryId is available on the context segment, can this be used to produce the results we are after?

At the moment we are trying to do this in Classic Procurement, although it would be good to know whether it would also be supported in RSSP.
