Can a group of nets be forced onto specific layers with CM?

I'm trying to see if I can use Constraint Manager in V17.2, to create a DRC if a group of nets are not kept on the same layer. For some FPGA bank routing the designer wants to ensure that routes within the same bank are kept on the same layer. Following this requirement is simple, but I'm not sure if a design rule can be created to force it and flag DRC's if it's not followed.

Can Constraint Manager control this?

    Hi Byron365,
    One thing you can do. You can define the layers for particular signals/group of signals you want. 
    By using electrical constraint >> wire>> layer set
    if not followed this there will be a DRC error.

    Cheers
