Exempting something from a timeloop

Is there a way of exempting one layer, or one parameter, within a timeloop?

For example, in this demo here (I don’t have the privs to upload attachments yet):

With the timeloop enabled, the clock hand swings round left to right once, and the letter changes: D->E->M->O.

With the timeloop enabled, the clock hand swings round left to right four times, but unsurprisingly the letter stays being a D.

The sort of thing I want is for the letter to be exempted from the time loop, so it changes but the clock hand swings round anyway.

This is a rather contrived example, and I know I could do that in other ways. In the real project there’s a loop over a sequence of transforms applied to a whole lot of items together, one of which has one parameter which changes every loop.

Thank youse!

Oh wait-- isn’t this what “free time” does?
