You could make them bi-directional as Sceadwian already suggested, or you might re-lable the outputs RST_N1 & RST_N2 and change the existing input port to RST_N1 and add another input port labled RST_N2 and jumper the two input ports together in Capture, or you could do the hard thing and get into the netlist and change the netnames if the version you are running will allow.
