You can't do it exactly like you want to using an encoder or a fader because there is no option to change the devices that they apply to.
You can however make some incremental buttons which may work for you.
To select your layers using a plus or minus button you can make a variable. Lets say you make a variable called layerselect and give it a value of one, which you can do by the command Vint,layerselect,1. You can then make a "plus" customscript button with 2 commands in it. The first command would be layerselect+ =1 which will add 1 to the value of your variable. The next command could be deviceselect,2,layerselect which will choose the next layer up on site 2. Do the same for a "minus" button but using layerselect- =1 for the first command.
You can then make incremental buttons, for example to adjust the x position you can have a "X POS +" button with the script DeviceSetParamRelative,2,layerselect,X Pos,0.50 which will adjust the position of your selected layer each time you click and then have a "X POS -" button with a value -0.50.
Not sure if doing it that way would be of any use to you. Of course this is all assuming that you are using STD.
