To create a 3 digit "Network" button you need to use the MACRO button.
First use the numeric draw button and assign each of the numbers.
Drag a Macro button onto your design, enter the assign mode and select the macro button. Next select each of the 3 digit buttons, that make up the Channel number. You will see them appear in the macro bar. Select each of these numbered buttons and insert a time delay of 0.1 or 0.2 sec by sliding the delay bar under the macro script. Select the Done button.
You can label the macro button or attach a Channel image for identification.
