Enhancement request - in ERPi can we get mapping by period?

Heather, we spoke about this but thought I'd post it also.  In ARM, you have profiles by period, but you don't have mappings by period in ERPi.  So when an auditor asked, what changed in the mappings (ERPi)?  We really don't know unless we remember to manually export the mappings each month then send those excel files.  Really like the concept of the master map in ERPi, then you would copy that to the period so you're in synch with ARM, Profile <-> ERPi Map. 
A sistuation came up where we had to repost a month earlier in the year, ARM was fine (we made a lot of changes but the profiles were good for that period) but we made significant changes to ERPi which caused some problems.  You're work around, creating locations by month is a good one but I'm pretty lazy and like buttons so a copy to period in ERPi would be awesome..
