Negative Inventory Adjustment Exceeding Committed and Picked Units

I am looking for guidance on how to alleviate the following example situation we encounter regularly during cycle counts:

Item has 100 units On Hand, 90 Committed, and 10 Available.

All 90 of those units are both Committed and Picked. They are not yet Packed or Shipped.

We cycle count Item A and find that we only have 80 On Hand. We make a -20 inventory adjustment so our On Hand quantity matches reality.

Because we adjusted down more than what was Available (-20 vs. 10), we are now overcommitted and over-picked on this Item.

Our current workaround is to check each item's Available count and make sure that the adjustment amount does not exceed it. If the adjustment would exceed the available count, we don't enter the adjustment and produce the required units to bring reality in-line with NetSuite On Hand count.
