Massive edit with search/replace strings

If I need to change a substring in many objects at once (ie change all "xxx" occurrences in "yy_z") it seems now I can do so only looking field by field in all my tables. I'd like to have a "search/Replace" feature which allows me to change strings or substrings in all my object names (tables, fields, indexes, ...) ....

Could  I hope so in the future?
