Bluemix Smaller quota buckets

We are a private bluemix customer with many organisations who are now starting to have fairly larger Organisation sizes.

When managing quota on their Org, we have found that as the quota sizes increase in by doubling in size.  When larger than 128gb they really are too large.  The quota management quickly becomes useless as the large bucket sizes mean we are forced to over allocate max memory available on our system. 

Please can we have option for smaller increments  64gb / 128gb.
