Would it be possible to increase the size of the Dimensional Augment Bag?

Last year, I purchased two Dimensional Augment Bags, one for Filigrees and one for Augments. The Filigree bag ran out of room last week. While I can divide up Filigrees into two Dimensional Augment Bags, I would really prefer they all to reside in a single container.

As an aside, for about 4 months, every time I brought home a batch of 30 to 40 Filigrees, I would carefully check them against my stockpile and sell the extras at low cost. In this way, I was trying to help people with much less time to quest and keep my Filigree bag under control. Each Filigree inventory check session takes 15 to 30 minutes. Eventually, it became too much. It was yet more adventuring time taken away from my avatar and other characters. I would love to sell excess Filigrees to those in need but the process takes too much time.

With the Filigree bag filled up, I once again find myself spending 10 minutes here and 15 minutes there pruning. I would prefer to spend that time adventuring.

Thank you for your consideration.
