Then what you do is to make a multi-unit symbol which has one unit per pot.
When you create this symbol, make sure:
a) that you specify the number of units,
b) That the "Units are not interchangeable" box is not checked,
c) when you draw the pot symbol (or an outline box) that it's "sharing" property "common to all units in component" is checked,
d) when you place the pins on the symbol, make sure that in the pin properties, "Common to all units in component" is NOT checked,
e) that the "edit pins per part or body style" is NOT selected,
f) and for each unit, you have to edit each pin's pin number to match what pin you want to use on the terminal strip.
g) Choose the footprint (the terminal strip) before saving the symbol in the schematic library. Call it something like "foo." Whatever.
Now, when you generate a BOM from the schematic, for this multi-pot thing you'll get a single entry called foo. It won't know about the terminal strip and it won't know about the pots or the wiring you need to hook it all up. You'll have to add those details to your BOM manually.
