Dimension goes to Dimension layer without user doing so possible?

Hi, V5
(V8 if ever I get time to set it up)
I wish that every time I create a dimension it gets allocaated to my DIMS layer (green)
is this possible,
…as I am fed up if having to activate dims layer then activate my object layer., back and forth during the build. or select the dims and then set to the dims layer.
V5 ?

or V8 ?

ideally V5 as stuck in V5 land, no time to set up v8 and test for V5 imports, sort out how it treats my V5 dims etc at the mo.

Cheers

Steve
