AutoCad :: Scaling Block Location On Viewport?

I have about 10 instrumentation enlarged plans that are drawing in model space and all the equipment text and instrument bubbles and blocks are in paper space.

All of the drawings are at 1/4" but they are getting loaded down with too much info, so we are cutting each of them into twenty drawings instead of ten. While I can change the view port very easily and scale it up accordingly, after I do that I will have to re arrange the text and blocks. I'm looking for a way to scale the blocks and text in a way to where it will change the location of the text and blocks, without actually changing the size. So I bring the drawings up from 1/4" = 1'-0" to 1/2" = 1'-0". If I scale all of the blocks up by 2, it will put them in the right location, but all of the text and blocks will be too large. I could select them all and change their scale down in the property palette, but I would still have to trim down all of the leader lines going from the instruments to their bubbles.

Long story short, is there a way to scale a block or text from a basepoint to where if you scale it, it will change it's location, but not the scale of the block or text?
