LT Spice M=4

I inherited a sim that has a capacitor with visible parameter M=4,
which means there are 4 such caps in parallel. M is a spiceline2
parameter.

But if I start with a plain cap, I can't find the way to specify a
spiceline2 param. Some parts have a right-click box with spicelines,
but a cap doesn't.

And I see parts with n=4 or x=4, which seems to mean the same as m.
