Multiple effect on 1 light.

I am running a ETC Ion Xe20. We have HPL lights (12 light Maxi) on lifts. We want to flicker the lights (a kind of a 4 spread chase) and to pulse in intensity from 30% to 80%. Ie two separate effect on 1 light. Any Ideas? Ended up doing the flicker with effect and using an inhibitor with the old school finger pushing.
