The Behavioral Current Source doesn't seem to have this option, or maybe it is set somewhere else?

Yes, it doesn't. It directly maps to a Spice 'B' source, whereas I suspect that the more basic current source is an improved model in LTSpice.
So if you're using that, I guess the only way you can add that feature is to include it in the formula expressing the current. Read LTSpice's help on "Arbitrary Behavioral Voltage or Current Sources". You'll find out there's quite a lot you can use for expressing the current.
