    You’ll need to add an expression to each layer seperately.
    An expression in one property can’t affect the value of another…

    Something like this would work:


    startvalue=value;
    endvalue=value+[10,10];

    linear(time,inPoint,outPoint,startvalue,endvalue);

    apply to one layer,
    then goto edit -> copy expression only
    select all other layers,
    paste.

    you can also try
    endvalue=value*1.1; or some other value

    for easier updating, link the actual value ([10,10] or 1.1) to a slider on a Null object, that way you can tweak it without changing 160 expressions.
