Alter visibility states across mutilpe layouts

I have creates dynamic blocks that are inserted using a lisp. Is there some way I can select blocks across multiple layouts and change the states once?

This will save me a lot of time if it is possible.

Thanks.

Of course you can.

(setq ss (ssget "_x" '((0 . "INSERT")(2 . "bname,`*U*"))))
(repeat (setq i (sslength ss))
              (process visibility state here)
             )

Building on Pbe's post, be sure to check for locked layer(s) before iterating the ActiveSelectionSet Object. Also be sure to limit the desired visibility state to those included in the AllowedValues Property for the Dynamic Block's Properties.

And probably also check the EffectiveName inside that loop, since the "bname,`*U*" will filter all the blocks (named bname) without any DB changes, but also all other DB's with a change (even those not inserted from bname).

Another thing you might do (if you also have the same block in Model space, but don't want to update that) is to include a (410 . "~Model") filter as well. That way it would select only blocks on layout tabs. Probably not needed as you'd very seldom have the same block in both PS & MS, but just to catch all possible scenarios.
