How to link the due date of a specific task or subtask into a custom field of a portfolio

[lpb]

I can confirm it’s working again for me after Asana’s deployed bug fix:

Potential bug with Rollup fields in portfolio - not showing number/formula fields available in projects

The deployed fix worked for our problem too–thanks! The only remaining issue for us is the minor missing “Due date” in the portfolio edit field as I showed in my earlier post, but it’s just a minor visual thing. Thanks!!
