Boundary scan insertion and input pad with enable

Hi,

 I am inserting boundary scan into a design and I have two LVDS pads which have a common enable signal that comes from another input pad.

One of the pads is an output and the boundary scan insertion correctly has a bcell element controlling the enable signal.

The input pad however is not controlled by the bcell element but the signal from the other input pad.

Is there a way to make the tool connect the bcell element to the input pad?

I have a IOSpecList with a section shown at the end of this post showing the input and output definition and the common controlling signal g1/z.

The only solution I can think of at the moment is to use edit_netlist.

Thanks,
