Hi Timothy,
We do not have exact plans on if/when this feature will be added to our plugin in the future.
You can also vote on this idea in our Feature Requests, as we tend to implement ideas based on customer feedback, so your input is greatly appreciated:

As far as customizing the start date, unfortunately that is beyond the scope of support that we can provide, as per our Support Policy.
If this functionality is a requirement for your intended project, I’d suggest that a third-party developer would be the best way to make this feature happen on a short timeline. ? We maintain a list of developers who work with our plugins on our Knowledgebase here:

Let me know if you have any other questions on this topic!
Thanks,
Jaime
