Can any AutoCad gurus help with this problem?

[Mr Pointy]

We have a number of Dynamic blocks with Text attributes & often need to move some of the attributes with respect to each other. I know that you can select multiple grip points using Shift-click but this can be very tedious. Does anyone know of a utility or maybe Lisp routine that will allow selection of multiple grip points by window or crossing, like you would with object grips?
