Group name updates don't reflect in the Explore filters

Last night we had to make a few changes to our group names. All we did was add one word to each group name to help clarify which business unit it belongs to. Explore reports look at the name instead of using a unique identifier so all of our dashboards were wrong this morning. They were all using the old group name which no longer exists. Please, please, please make it so that it uses a unique identifier so future changes do not mess up reporting. As our business changes and we re-org and/or expand our business units we will probably need to make other edits. Having to fix all queries on dashboards each time in a real pain.
