Comp Markers to Time Remap?

Hello,

I'm in need of an expression  whereby a marker value in one comp will drive/equal the time remap value of another comp.

as an example:

Within a comp (MarkerComp1), I have a layer (MarkerLayer1) in which the comp marker value is set to 20
In my second comp (TremapComp2)  I have a Time remap layer (TrmapLayer2) in which I would like this to equal 20 as well.

Can this be done?

Thanks for any help

Jeff
