The Create Differential Pairs From Nets dialog provides controls to create differential pair objects using net names conforming to a naming convention with a common prefix, followed by a consistent positive/negative suffix, for example, TX0_P and TX0_N.
The dialog is accessed from the PCB panel by clicking the Create From Nets button (lower left area of the panel) when in Differential Pairs Editor mode.
The filters at the top of the dialog can be used to show net pairs based on existing net names.
