Welcome to the forum Dannyboy.
I am quite partial to Lee Mac's Layer Director lisp, and have added the VIEWPORT commands with a wildcard, so that when creating a viewport it is created on the MVIEW (modelview) layer. If the layer does not yet exist in the drawing it will create it, switch to that layer, and after you have specified where you want the viewport it will return to whichever layer you started the lisp from.
I, agree with ReMark, and see no advantage whatsoever to putting viewports on the DEFPOINTS layer, seems like a bad idea to me. Just make sure that you set your MVIEW layer to not print.
If I am dimensioning or checking a drawing I want to be able to see the viewports while I am doing it.
I also am quite inclined to agree with Blackfish's (welcome to the forum, by the way) postscript note.
If the time spent accessing a specific tool to do something, is greater than time required to do something without that tool?
What is the point?
I run LAYER DIRECTOR nonstop, and it is awesome.......on so many levels (or layers).
Volume and repetition do not validate opinions forged in the absence of thought.

Working with LT I have a poor subsitute of Lee's Layer Director using modified command for text, dimensions, viewports, and hatches revclouds etc. I had to modified all of them by hand. And I cannot return to the previous current layer with some commands for example using "_layerp" e.g.
^C^C_-layer;m;VPORT;;tilemode;0;_-vports \\tilemode;1;layerp; <-- it works here with "vports"
^C^C_-layer;m;DIM;^C^C_dimlinear \layerp; <-- but not there with "dimlinear"
^C^C_-layer;m;TEXT;^C^C_dtext \layerp; <-- or "dtext"
^C^C_-layer;m;REV;^C^C_revcloud \layerp; <-- or "revcloud".
