Newbie question.....simple, but possible?

Actually a pre-Newbie, as my Voyager has not arrived…but something I like to do with software synths is to have an LFO king in for vibrato AFTER a note has sounded for a set amount of time. I mean doing this without using any additional performance controls, freeing up my other hand for other tasks.
It occurs to me that I can use aftertouch, but say I want to use that on the filter. Is there a way to achieve this?

set your vibrato settings in mod buss 2 with amount at zero and use an expression pedal plugged into mod 1 input to add in the vibrato.

…or aftertouch…

No LFO delay no matter what.
