One of my favorite answers is "Because!"
In this case the process to get something added is:

1. Submit it here https://accountants.intuit.com/community/proconnect-tax-idea-exchange/idb-p/605

2. Hope a large group of users vote for it.

3. While you are hoping, you also wait as it slowly meanders it's way through the process to maybe get adopted into the software

In the meantime create a pdf or word doc that you can add on your own.
