Move modules to submodules question

[joshua.kimball at gmail.com]

I have a set of utility modules that were all added to a folder called (util_mods). Recently the set of modules grew to be too large and I've been working on splitting it up into sets of sub modules, for example, util_mods\set_a. The issue is that if I start moving modules to sub folders I have to go through and update literally thousands of scripts that import the module from util_mods. I was wondering if there was a way to move these modules into submodules while still maintaining the imports. For example "import util_mods.moda " would actually import as "util_mods.set_a.moda".

My longterm goal is to update the scripts to point to the correct submodule/module however I was hoping for a short term solution to this so I can make the change immediately and update the other scripts over time.
