The original poster's query is one that has been asked before here by
others -- most likely those having experience with another "computer
algebra system".
It might be very convenient to have such a command in Mathematica, too.
It's effect would be to add the conditions to the rule base, and then
the rule could be used by those other commands that now, or in the
future, are affected by Assuming.
Of course a global assumption can be dangerous, but no more dangerous
than any global assignment.
