I love the addition of the unlocking and matching gift features in the hub. I think it would be even better if you have the option to turn on the challenge for a certain time period. For example, we have a challenge that $20,000 will be unlocked if 200 gifts are made in one day. I would like to be able to say it is active on March 3 from 8:00am - 11:59pm. We have similar challenges over the course of our giving campaign. There is not an easy way to tie gifts made during a certain time period to the campaign. We only have one fund so I can't track based on funds. My current workaround is a form question that we set to a default for each challenge in the hub. I don't want to use the challenge option because it doesn't show the progress.
