Default grouping bits to form bus in VCD file


I just have another issue. I try comparing the VCD files generated by
Modelsim to a reference VCD file. Unfortuantely this is not working,
because the modelsim represents a 32-bit signal as 32 single bits
whereas the reference VCD file treats the whole 32 bits as a bus.

So is there a way to group single bits in VCD to a single Bus?

Modelsim VCD has single bits

pipe.arc_fe_dc.fe_dc[31] Q+ from regr.vcd
pipe.arc_fe_dc.fe_dc[30] R+ from regr.vcd
pipe.arc_fe_dc.fe_dc[1] o+ from regr.vcd
pipe.arc_fe_dc.fe_dc[0] p+ from regr.vcd

Reference VCD looking for a bus of 32 bits and outputs error:
NO match pipe.arc_fe_dc.fe_dc[31:0]
