scale multiple objects while keeping the base point

[ssj4lucapc]

Good morning, everyone! a question..I wanted to know if it is possible with a command of autocad(2014) or with some lisp scale in one shot only more objects but making sure that each one of these maintains fixed its base point and does not move compared to a single base point for all selection.
thanks for the attention and good work to all!

if you do it with the blocks instead it is possible through the board of the properties but only of a scale, not reduction ratio, equal for all; otherwise a lisp could be this, but I can't verify it because I have lt

In fact, you're right about the blocks, I know. Let's say that my problem is about retinals... basically I have a sewer line with a series of square nets that indicate the individual wells. I hoped there was a way of climbing them all at once but at this point, not being blocks, I think there is little to do... :
